By seeing the basic deifinition v=ds/st and a=dv/dt, so for a free fall of a body the acceleration of the body remains constant its graph will straight line parallel to the time axis, velocity graph will be one degree higher as it is obtained by integrating acceleration, hence its graph will be one degree higher and will be inclined at some angle and the graph of displacement will be still one degree higher (i.e. parabola)
notes: 1) area under the velocity time diagram for a given time interval is equal to the displacement over the interval 2) similar area under acc time diagram gives velocity over that period.
On earth, the acceleration due to gravity is a constant 9.8 m/s2 so a graph of acceleration vs time would have the equation a = 9.8 m/s2. As said above, the graph of acc. vs t would be a horizontal line (zero slope) with a y-intercept of 9.8 m/s2. The area under this line is a rectangle with a width, t, and a height of 9.8 m/s2, so change in velocity is given by delta v = (9.8m/s2) t. The area under this line is a triangle with a height of delta v and a base of t, so the equation for change in position or displacement is delta x = 1/2 (delta v)(t) or delta x = (4.9 m/s2)t2
If you know the equation of the displacement vs time graph for freefall (delta x = 1/2 g t2 where g=9,8 m/s2), get the graph by plotting delta x for various times. From that graph, find the slope of the tangent to the curve (A TI-83 calculator can do this) at various times. Plotting slope of tangent vs time gives you a velocity vs time graph. Plotting the slope of the velocity/time graph vs time gives you the acceleration vs time graph.
Who invented the kinetic energy?
The concept of kinetic energy was introduced by Johann Bernoulli, a Swiss mathematician and physicist, in the 18th century. He defined kinetic energy as the energy possessed by an object due to its motion.
What causes a musty odor when heat is turned on in a 1998 explorer?
IT IS USUALLY CONDENSATION FROM YOUR AIR CONDITIONING, IT GROWS MOLD AND BACTERIA. WHICH WILL SIT THERE ALL SUMMER AND WINTER. HOWEVER IN THE WINTER WHEN YOU BLOW YOUR HEAT IT WARMS UP THE BACTERIA AND MOLD. THERE IS A PRODUCT CALLED FRIGI-FRESH MADE BY B.G. WHAT YO NEED TO DO ONCE YOU GET FRIGI-FRESH IS SPRAY IT IN THE FRESH AIR INTAKE. USUALLY LOCATED BETWEEN THE WINDSHIELD AND HOOD. WITH YOUR AC ON FULL BLAST. SPRAY THE WHOLE CAN. THIS SHOULD FIX YOU UP
Why would a 1999 Ford F150 V6 have sluggish acceleration only below 35MPH?
Sluggish acceleration at low speeds in a 1999 Ford F150 V6 could be due to issues with the fuel system, such as clogged fuel injectors or a dirty fuel filter. It could also be caused by a malfunctioning mass airflow sensor or a problem with the transmission, such as a clogged filter or low fluid level. It's best to have a professional mechanic diagnose and address the specific cause of the issue.
Why does the 1992 Grand Am lose power after it reaches 40 miles per hour?
Both times that this has happened on my 2001 Buick Regal AND 2001 Grand Am it has been a clogged Catalytic Converter. Both times it was covered by a blanket 120,000 mile warranty regardless of whether or not you are the original owner. Take the car to a reputable GM dealer for this.
I am a used car dealer and sell tons of vw's. I have had several beetles that dont register speed, fuel or rpms correctly. the only way I have found to make it close without taking it to the shop is remove the glass covering the spedo cluster and pull off the red needls and place them at zero. not sure how close to correct it is but I do think it is close.
How can you get a round bubble butt?
To achieve a round bubble butt, you can focus on exercises that target your glutes, such as squats, lunges, hip thrusts, and deadlifts. It's important to also maintain a healthy diet and be consistent with your workouts to see results. Additionally, incorporating resistance training and progressive overload is key to building muscle in that area.
How do you change a velocity joint in a 1996 Chevy Corsica?
To change a velocity joint in a 1996 Chevy Corsica, you will need to first lift the vehicle and remove the wheel. Then, disconnect the drive shaft from the transmission and remove the old velocity joint. Install the new velocity joint, reconnect the drive shaft, and put the wheel back on before lowering the vehicle.
What is slow binding kinetics?
Slow binding kinetics is when kon is very slow in the relationship Kd =kon/koff.
For slow binding inhibition, it is when inhibitor binding to an enzyme results in a conformation change that doesn't allow the ES to form, eliminating the formation of product. This is demonstrated as:
E + I --> EI* -X-> P
The vibration at speed is more than likely a tire out of balance or a tire with a broken belt. Have this checked ASAP. The pulsation during acceleration can be many things, from a vacuum leak to a clogged fuel filter. Take it to a tech for service.
How can you increase the top speed of a 2002 Ford F-150 with a 4.2 liter engine?
first off. its a 4.6 liter. pop into your local performance shop and pick up a super chip designed for the truck. one of the most popular in my area for gas engines is the brand Bully Dog. i use one myself, and for a gas engine its gives pretty good response. also shows your instant MPG or consumption. Transmission temp. and a few other nice perks. has multiple settings for different increases and also has a fuel saver option for the lazy days. in my books that's the best way to go. anything else voids warrenties and has the ability to disable the trucks. the governor has a safety tag built in. when pulled and not dummied the truck wont start. better off to keep it simple. and pik up a chip. also bully dog is a heads up display system so u can set it while cruising and u don't have to park and play around with a bulky set tool.
Why would an 88 Jeep Wrangler not go faster than 55 mph?
That's a tough question. I need a little more info. Does it seem to lack power close to 55? does it have power before 55? Believe it or not. But check out your Cataletic converter. It maybe clogged up. Catalytic Converters have like a honeycombed internal webbing inside. When it heats up it sweels. If it is clogged it will sweel up and it will cause back pressure to be forced back into the motor causing loss of power and not going over 55. I would check that first. I good test ,is to start the Jeep and put a peice of paper over the hole of the exhaust pipe. If it sucks in the paper, It is clogged. Hope that helps out some. If you mean that the engine seems to really be racing at 55 mph, that is normal. The tranny only has three gears, and the first two are very short. Third gear can only go so far. Combine that with an engine designed for low-speed operation, and you've got yourself the legendary Jeep of old. At least, that is true with my 87 Jeep Wrangler. 60mph really seems to be pushing the limits of comfort for that engine-tranny combo. Great for low-end torque, bad for high-end speed.
What is a safe speed for a child on a slide?
A vehicle's momentum depends on its?
A vehicle's momentum depends on its mass and velocity. The momentum of a vehicle is the product of its mass and its velocity. The larger the mass or velocity of a vehicle, the greater its momentum.
Is there a relation between inertia and friction?
Inertia and friction are related in the sense that friction opposes the motion of an object due to inertia. Inertia is the tendency of an object to resist changes in its state of motion, while friction is the force that opposes the relative motion of two surfaces in contact. The presence of friction can affect an object's motion by counteracting its inertia and slowing it down.
Can an object move in a circular path without being accelerated?
"yes move a remote controle car on a patch of low friction ground and move it in a
circle. basic physics"
I believe the answer above is not true. Newton's first law (basic physics) states:
Every object in a state of uniform motion tends to remain in that state of
motion unless an external force is applied to it.
A circular path is not a uniform motion. Moving a car around in a circle means that
it is being accelerated towards the center of the circle. If you could do the above
experiment under perfect "frictionless circomstances" then the toy car would
eventuall come to a stop, without using the brakes (provided the car is not being
propelled forward by its engine).
I'm no scientist, but I do not think it is possible for an object to move in a circular
path without having to accelerate it towards the center of the circle, unless you
can somehow bend time-space (like gravity does).
When an object is moving in a circular path, it's constantly changing it's direction.
thus the velocity is changing. Change is velocity states that the object is accelerating.
=======================================
The problem that everybody above this line is having is: They're trying to stay
consistent with the universally held but mistaken idea that 'acceleration' means
'speeding up'. It doesn't !
'Acceleration' means 'any change in speed or direction of motion'. That could mean
speeding up, slowing down, starting out from a stop, rolling to a stop on grass, or
moving along any path that's not a straight line. They're all 'acceleration'.
An object moving in a circular path is constantly changing its direction of motion,
so there's acceleration there. An object can not move in a circular path without
acceleration, because the very bending of the path away from a straight line is
acceleration. Regardless of what's happening or not happening to its speed.
No, "mph" is not capitalized unless it is at the beginning of a sentence or part of an acronym. It stands for "miles per hour."
What happens to k.e. of a bullet when ita penetrates into a target?
When the bullet penetrates into an object its velocity decreases very much or becomes 0 suddenly. This causes a change a momentum of bullet and impulse is applied. Technically the kinetic energy is converted to potential as a deformation occurs inside that object, transferring some of the kinetic energy into the object.
What make a basketball bounce higher helium or air?
Helium will make a basketball bounce higher because when it is put into the basketball the air particles move faster and faster causing the basketball to bounce higher.
Potential energy is a fundamental concept in physics and plays a crucial role in understanding the behavior of physical systems and the conservation of energy. When the conditions or positions of objects change, potential energy can be converted into other forms of energy, such as kinetic energy or thermal energy, as objects move or undergo changes in their state.
Will it take a person traveling 40 mph to visit a place this 60 miles away?
Yes, it will take the person 1.5 hours to travel to a place that is 60 miles away at a speed of 40 mph. This is calculated by dividing the distance (60 miles) by the speed (40 mph), which gives the time it takes to cover that distance.
Does a speeding car or a jet on a runway have more inertia?
A speeding car and a jet on a runway would have roughly the same amount of inertia, as both objects have mass and are in motion. Inertia is a property of an object that resists changes in its motion, and is directly proportional to the object's mass. Therefore, the greater the mass, the greater the inertia.
What potential energy does a squashed ball have?
When a ball is squashed, it gains potential energy due to the compression of its material. This potential energy is stored in the form of elastic potential energy, as the ball has the potential to return to its original shape when released.
What is 126 miles per hour when expressed in seconds?
To convert miles per hour to seconds, you need to know the distance covered in a specific time period. Miles per hour is a unit of speed, while seconds are a unit of time. Without additional information, it is not possible to directly convert 126 miles per hour into seconds.
