Question

1. an object that has kinetic energy must be

a. lifted above earth’s surface
b. at rest
c. in motion
d. none of the above

Explanation:

Kinetic energy is the energy an object possesses due to its motion. By definition, an object with kinetic energy must be in motion. Option A refers to gravitational potential energy (related to height above Earth's surface), option B is a state of rest (where kinetic energy is zero if at rest with respect to the reference frame). So the correct answer is based on the definition of kinetic energy.

Answer:

C. in motion
