Does the speed of a position time graph of an object gives the speed of the object?
No, but the slope of the graph does.
Is there a connection between absolute zero and potential and kinetic energy?
Absolute zero is the (theoretical) limit at which all molecular movement stops (that means that the total kinetic energy of all the molecules in the substance being cooled to absolute zero becomes zero).
I'm not exactly sure, but since I know that Usain Bolt ran a top speed of 27.9 mph in his 100m world record of 9.58 s, I would guess that Asafa Powel ran maybe 25-26 mph when he ran 9.72 s.
Kinetic Energy = 1/2 * mass * velocity squared
KE = 1/2mV2
KE = 1/2(35 kg)(1 m/s)2
= 18 Joules

How is instantaneous acceleration related to a velocity-time graph?
Acceleration is the derivative of velocity (a=dv/dt). If you are not familiar with calculus then it would be sufficient to say that the slope of the line tangent to the graph, only touches at one point, is equal to the instantaneous acceleration.
When is a body said to possess kinetic energy?
A body is said to possess kinetic energy when it is in motion. Kinetic energy is the energy an object has due to its motion and is dependent on both its mass and velocity.
'Mach ' is the speed of sound. This depends on air pressure and temperature. On a median day at sea level this is normally 761 mph. That figure can vary if air conditions are changed, but based on this common number, mach 4.5 is 3,324 mph.
How jump is possible in space as there is no reaction force?
I assume you mean micro gravity or in free fall when you write "space" You (the jumper) has to push on something.
Once you have jumped off something you will continue (as Newtons laws of motion propose) until you are stopped by another force.
Where does kinetic energy go after it is used?
If you're suggesting something like an auto accident, the energy of the collision is used to deform materials in the structural elements of the vehicle(s). It also heats them. The primary design features of cars includes a lot of thought to where the energy of a collision can go. Bumpers collapse, body panels and their strengthening members fold and become compressed, and a top or roof can collapse down. All this sinks ("sucks up") energy. And if it all works in an optimal way, you can climb out and walk away.
What is the formula for the total kinetic energy of a moving body?
The formula for the total kinetic energy of a moving body is KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the body, and v is the velocity of the body.
How does a gust of wind move dust - dirt - and other particles?
The atoms, molecules, and small particles in air have mass. Wind is the name we give to a moving mass of air. Moving masses possess kenetic energy. Some of this energy can be transfered by collision, to dust, dirt and other particles on the ground, so they are forced to move too. A leaf blower makes use of this principle.
How do you set up the conversion of 35 kilometers per hour to meters per minute?
To convert 35 kilometers per hour to meters per minute, you first need to convert kilometers to meters by multiplying by 1000 (since 1 kilometer is 1000 meters). Then, to convert hours to minutes, you need to multiply by 60. Therefore, 35 kilometers per hour is equal to 583.33 meters per minute.
What are factors that affect an object's kinetic energy?
The factors affecting kinetic energy are mass and velocity.
9.5 * 1000 * 1000 / 25.4 / 36 / 1760 = 5.903 mph

How does projectile motion compare with Magnus effect?
Projectile motion refers to the motion of an object moving through a gravitational field, such as a ball thrown in the air. The Magnus effect, on the other hand, is a phenomenon where a spinning object experiences a sideways force perpendicular to its direction of motion, affecting its trajectory. In essence, projectile motion is a general term for the motion of objects in a gravitational field, while the Magnus effect is a specific effect caused by rotation.
What is 2 yards per second in mph?
There are 3600 seconds in one hour. Therefore, 2 yards per second is equal to 2 x 3600 = 7200 yards per hour.
There are 1760 yards in one mile. Therefore, 7200 yards per hour is equal to 7200/1760 = 4.09 recurring (that is, 4.090909...) miles per hour.
So the potential energy is the energy in the car at the top of the first slope.
It changes into kinetic energy (Speed with mass) as it rolls down the hill.
Then the electric motor winds it back up the hill, putting potential energy in the system again.
How does increasing mass effects kinetic energy?
Increasing mass directly impacts kinetic energy, as kinetic energy is directly proportional to mass. The formula for kinetic energy is KE = 0.5 * mass * velocity^2, so as mass increases, kinetic energy will also increase.
How do you find kilometers per hour from meters per hour?
To convert meters per hour to kilometers per hour, you need to divide the meters per hour value by 1000 as there are 1000 meters in a kilometer. So, the formula is: kilometers per hour = meters per hour / 1000.
Where does the water have its maximum kinetic energy and minimum gravitational energy?
The water has its maximum kinetic energy at the bottom of a waterfall where its velocity is highest. It has minimum gravitational energy at the top of the waterfall before it starts to fall, as it has not yet gained significant potential energy from being at a higher elevation.
What are the damage of friction?
All energy ultimately ends up as heat, thus, all physical processes' ultimate 'waste' products is heat Friction always creates heat, and an increase in friction always creates an increase in (waste) heat...remember Second Law of Thermodynamics, right? Thus: Friction increase increases heat; increases waste and thereby decreases efficiency, without even considering the damage that the increased heat can create
What graph of acceleration vs time constant velocity?
When the acceleration of a particle is constant, the velocity will be increasing at a constant rate. This means that the velocity versus time graph will appear with a straight line "slanting up to the right" in the first quadrant. With time on the x-axis and velocity of the y-axis, as time increases, velocity will increase. That means the line will have a positive slope. The higher the (constant) acceleration, the greater the slope of the line. If we take just one example and mark equal units off on our axes, and then assign seconds along the x-axis and meters per second along the y-axis, we can plot a graph for an acceleration of, say, one meter per second per second. Start at (0,0) and at the end of one second, the velocity will be one m/sec. That point will be (1,1). After another second, the velocity will be 2 m/sec owing to that 1m/sec2 rate of acceleration, and that point will be (2,2). The slope of the line is 1, which is the rate of acceleration.
What is the relationship between weight and kinetic energy?
Kinetic energy is the energy of motion. The amount of kinetic energy an object has depends on the mass of the object and the speed of the object. The equation is: K= (1/2)mv^2, where K=kinetic energy, m=mass, and v=speed of the object.
What is the definition of velocity time graph?
A velocity-time graph shows how an object's velocity changes over time. The slope of the graph represents the object's acceleration, and the area under the curve represents the total displacement of the object. It is a useful tool for understanding an object's motion.
