Thank You for points dear !

Answer 2

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

Perhaps the most important property of kinetic energy is its ability to do work. ... If we want to change the kinetic energy of a massive object, we must do work on it. For example, in order to lift a heavy object, we must do work to overcome the force due to gravity and move the object upward.
