F = ma When a force is applied to accelerate an object from speed

F = ma When a force is applied to accelerate an object from speed v 1 to speed v 2, the work done on the object can be written as:

Kinetic Energy Since this work is done to increase the speed of the object,

Kinetic Energy Since this work is done to increase the speed of the object, the energy that is increased is the object's kinetic energy Ek:

Kinetic Energy Since this work is done to increase the speed of the object,

Kinetic Energy Since this work is done to increase the speed of the object, the energy that is increased is the object's kinetic energy Ek: Kinetic energy is therefore:
