When velocity is changing what is happening to the slope on a position versus time graph?
That slope is the 'speed' of the motion. If the slope is changing, then the speed
is changing. That's 'accelerated' motion.
(It doesn't matter whether the speed is growing or shrinking. It's still 'accelerated'
motion. 'Acceleration' does NOT mean 'speeding up'.)
What is 186000 miles per second in centimeters per second?
186,000 mph = 83.15 kilometers per second.
How many drops per second are necessary to create a stream?
It depends on the flow rate of the stream. Typically, thousands of drops per second are needed to form a continuous stream visibly.

40 'kilometers per hour'. It is equal to 24.86 miles per hour.
Is it true that you find acceleration when initial velocity final velocity and time are given?
With that information, you can find the average magnitudeof the acceleration
during that period of time. You can't tell what either the magnitude or direction
were at any time during, only the average magnitude for the whole interval.
Is the inertia of a body equal to its mass?
Inertia is related to the mass, and it is proportional to the mass. When measuring things, you will usually measure the mass, not the inertia - but it basically amounts to the same. Just consider the mass to be what gives an object its inertia.
What happens to kinetic energy and potential energy of a car when it accelerates up a hill?
What happens to kinetic energy when your car stops at the end of the track?
It's all about energy?
The first question to ask yourself is," What stops your car?
Most people would say, "The brakes stop the car."
What happens to the brake as the car is stopped?
Due to friction, they heat up and the brake pads wear out?
What does it mean for brake pads to wear out?
The brake pads get thinner as they rub on the spinning rotor.
What causes them to get thinner?
The friction breaks the chemical bonds in the material of which they are made.
The Kinetic energy is converted into heat and used to break the bonds between the molecules in the material of which the brake pads are made.
If you push hard enough on the brake pedal, the tires will stop turning, and the car will skid to a stop. In this case, the tires will give off heat due to friction and the tires will wear thin as the chemical bonds between the molecules in the material of which they are made are broken.
Good site for explanation of brakes!

What are kinematics when applied to secondary machining techniques?
Casting, forming, forging, extruding and molding are primary machining. Material removal and change of shape, drilling, grooving, dimensional corrections are some very special specific techniques, which are used in specialist workshops or machines are suppose to be the secondary machining, Turning, milling, drilling grinding, shaping are some of the secondary machining process. Chuck, face plate, vice, jigs, fixtures special centers are the work holding devices. Vernier calipers, micrometer, compactors, depth micrometers are some of the measuring tools using for secondary machining Turning, threading grooving, parting tools, milling cutters, taps drill bits, etc are cutting tools using for secondary machining techniques. Cutting speed, Speed, Feed rate, etc are the cutting parameters Inspections, verification, comparison, are the quality control methods in this kinematics. Assessments of health and safety measures are yet another kinematics in this technique.
29 kilometers per hour is equal to approximately 18 miles per hour.
How fast was Jackie Robinson in mph?
Jackie Robinson was known for his speed on the baseball field and was estimated to be able to run the 100-yard dash in 10 seconds. This would equate to a speed of approximately 18 miles per hour (mph).
When winds inside a tropical cyclone reach 74 mph what occurs?
When winds inside a tropical cyclone reach 74 mph, it is classified as a hurricane (Category 1) in the Atlantic basin and a typhoon in the Pacific. At this wind speed, a tropical cyclone becomes more organized and can cause damage to infrastructure and pose a threat to life and property.
What is a tropical has winds between 40 and 73 miles per hour?
Yes. A tropical storm has sustained winds of 39-73mph.
Whereas impulse involves the time that a force acts work involves what factor?
Work involves both the magnitude of force and the distance over which the force is applied. Work is calculated by multiplying the force exerted on an object by the distance the object moves in the direction of the force.
How many mph is 100 yards 11 seconds?
To find out how many mph is 100 yards in 11 seconds: First, convert 100 yards to miles (100 yards = 0.057 miles). Next, calculate the speed by dividing the distance (in miles) by the time (in hours) - 0.057 miles / (11 seconds / 3600 seconds) = 19.64 mph.
How much time for 260 miles at 80 mph?
about 5 hours and 45 minutes You can find the answer by dividing 430 by 80 to get 5.375 hours. To convert tenths of an hour to minutes, multiply .375 by 60 and you get 22.5 minutes. So the answer is 5 hours and 22.5 minute (if you don't stop).
1 mile = 1.609344 km
→ 17 mph = 17 × 1.609344 km/h ≈ 27.4 km/h
The ball stops bouncing due to a loss of energy through various forms such as heat, sound, and deformation of the ball. As the ball bounces repeatedly, these energy losses accumulate, causing the ball to eventually come to a stop.
A kilometer (km) is 5/8 (or 60%) of a mile. So 330 kph x .6 = 198 mph. Or times 330 x .621=204 mph
Quick & easy (& approximate) calculation learned while driving in Germany... multiply by 6 and drop the last digit... 6 x 330 = 1980 = 198mph
How much is 80 miles per hour in kilometers?
There can be no equivalence. Miles per hour is a measure of speed while a kilometre is a measure of distance. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
29 Nautical miles per hour (aka knots) is 33.37 statute miles per hour.
A nautical mile is 6000 ft while a statute mile is 5280 feet
When pendulum stops has the kinetic energy changed to potential energy?
As the pendulum stops swinging, its maximum kinetic energy (the initial energy at the beginning of the swing) decreases, and its potential energy increases. Once the pendulum stops, it will have zero kinetic energy and maximum potential energy.
Is illumination possible in the absence of an observer?
In the absence of an observer, illumination as a physical process can still occur, such as light shining on an object. However, the perception or experience of illumination requires an observer to interpret and be aware of the light.
When a pendulum is at the center position what is true of the kinetic and potential energy?
If a pendulum is at its center position, then there are two possibilities:
1). It may be swinging. Then its kinetic energy is maximum and its
potential energy is zero.
2). It may be stopped altogether. Then it has no energy at all.
When a book falls to the floor what happens to the potential energy?
When you drop a book the original potential energy is converted into the kinetic energy, When the book hits bottom the kinetic energy is absorbed by the surface underneath and some is converted to sound energy.
This maintains the law of conservation of energy. the total amount of energy in this universe is constant and remains constant. Energy can neither be created nor destroyed it can just change its form from one form to another.
