Answer:
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:
Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. ... Note that energy is a scalar quantity, i.e., it does not depend on direction, and it is always positive SI unit of kinetic energy is JOULES
CGS unit of kinetic energy is ergs(10^-7J).
