It's C. The mass and speed of an object. There are mainly two factors on which Kinetic Energy (denoted by KE) of an object depends - the mass (m) and speed (v) of the object. If the mass and speed of an object will increase, its KE will also increase. The equation which is used to...Read More

Kinetic energy is possessed by an object, by virtue of its movement. It is dependent upon mass and velocity. Potential energy is also affected by its position or state. However, it is more closely linked with forces such as the force of gravity. While kinetic energy of an object is compar...Read More

Yes, you can. If you are swinging a punch you have created kinetic energy and if you decide to stop that punch in mid-air then you have "destroyed" the kinetic energy that was in the punch.

A ball rolling down a hill would have the greatest kinetic energy. It helps the ball to keep moving down the hill despite all the forces trying to stop it. The energy comes from the forces trying to stop it. The energy comes from the force of gravity, as the object rolls down the hill. If there...Read More

A car driving down the hill will have the greatest kinetic energy. Kinetic energy is a concept that is of extreme importance in Physics, and it specifically comes under the domain of classical mechanics or Newtonian mechanics. Kinetic energy can be defined as the energy that is possessed by...Read More

No work...
W = (Fcosθ)d ; W=work, F=force, d=distance/displacement
...
its prerpendicular so cosine 90° = 0 then multiply so W = 0
