A moving ball possesses mechanical energy due to both its high speed and its vertical position above the ground (Kinetic energy + potential energy).

A.     Kinetic energy

This is the energy an object has got because it is moving.

Mathematically the kinetic energy of an object  is:

Where, m represents the mass of object (kg); v is the speed of object (m/s) and KE, kinetic energy (Joule, J).
