Question

what is kinetic energy ?​

Answer 1

Answer:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Answer 2

Answer:

Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. ... This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.
