Q

An object that has kinetic energy must be:

A. At an elevated position

B. Falling

C. At rest

D. Moving

A

Answer: D. Moving

The energy possessed by a body in motion is known as kinetic energy. Kinetic energy is defined as the work needed to accelerate an object of a given mass to a stated velocity from rest. In other words, an object that possesses kinetic energy must be moving. When a body is in motion, the body maintains the kinetic energy unless a change in speed occurs or an external force is applied to such a body. Kinetic energy has the joule as its standard unit.
