Answer :
KE = 2mv2 is the formula used to determine kinetic energy. The relationship between kinetic energy and an object's mass and square of its velocity is direct.
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed. In physics, an object's kinetic energy is the energy it has as a result of motion. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes. The body exerts the same amount of effort when slowing down from its current pace to a condition of rest. Formally, a kinetic energy is any term that includes a derivative with respect to time in the Lagrangian of a system. This is a fair approximation in relativistic mechanics only when v is considerably slower than the speed of light. The English unit of kinetic energy is the foot-pound, while the standard unit is the joule.
