Answer:
Newton's second law
Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
Explanation:
Explanation:
Potential energy is the energy obtained by an object due to the position of an object. Whereas kinetic energy is the energy obtained by an object due to its motion.
For example, an ball is placed over a building of height h. Then steps followed to covert its potential energy into kinetic energy are as follows.
Step 1: When ball is at placed over a building of height h, then it has only potential energy and no kinetic energy.
Step 2: A man pushes the ball and it moves in the downward direction.
Step 3: When ball starts to move or fall it gains kinetic energy, that is potential energy now becomes equal to 0.
Similarly, on reaching the ground and after bouncing a few times when it stop moving then kinetic energy converts into potential energy.
