Detailed explanation-1: -Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.
Detailed explanation-2: -Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
Detailed explanation-3: -Kinetic energy is the energy that an object has as a result of its movement. That means when a body is in motion it possesses kinetic energy. Kinetic energy can never be negative and is a scalar quantity, meaning it only provides the magnitude and not the direction.
