Kinetic energy of an object can be defined as the energy of the object or mass in motion. Any object which is in motion will have some kinetic energy irrespective of direction of motion (horizontal or vertical). The object gains kinetic energy in motion, during acceleration and the body maintains this kinetic energy unless its speed changes.
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity.
K.E. = 1/2 mv²
Where, m is the mass of the object and v is the velocity with which it is moving.
