And are facing each other of the two and the friend are on the separate more you when the moving. Your friend weighs a lot on you is push off of each other, the force exerts you exert on him. Less than

Two objects are raised off the ground and one of them is three times as high as the other one. How do their potential energy compare?

The distance between starts is usually measured in A. Light-years B. Kilometers C. Astronomical units D. Miles Physical properties used to measure stars include A. Mass B. Brightness C. Size D. All of the above An H-R diagram A.

As a cat pounces on a mouse, its muscles consume 10 units of potential energy (which the cat previously gained from the food it consumed). However, the pounce itself only required 4 units of kinetic energy.

4. You bought a block of cheddar from the grocery store. If you cut a small piece and a large piece from the same block of cheese, will they have the same density?

The table shows information about four students who are running around a track. Which statement is supported by the information in the chart? Autumn has more kinetic energy than Chiang. Mohammed has less kinetic energy than Autumn.

Are microwaves and radio waves faster or slower than other types of electromagnetic energy?

If you dive under-water, you notice an uncomfortable pressure on your eardrums due to the increased pressure. The human eardrum has an area of about 70 mm2 (7*10-5m2), and it can sustain a force of about 7 N without rupturing.

Why cant kinetic energy ever be greater than potential energy

For a stationary observer, when the source of a sound is moving, its pitch appears to change.

Give an example of each simple machine
