The work-energy principle states that the net work done on an object changes its kinetic energy. While work done by propulsive forces, such as driving force of an engine, increases kinetic energy, work done against resistive forces, such as forces from the brakes, will cause kinetic energy to be lost. Considering the work-
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
Energy is defined as the capacity to do work and comes in different forms: Gravitational potential energy - this is dependent on the object’s position in a gravitational field and its mass.
What is Work, Energy and Power? Work: Definition: The work done by a force is defined to be the product of component of the force in the direction of the displacement and the magnitude of this displacement. Formula: Work can be calculated by multiplying Force and Distance in the direction of force as follows. W = F × d: Unit

1 joule=1N.1m Power. Power is the rate of work done in a unit of time. The unit of the power from the equation given above, joule/s, however, we generally use the unit of power as watt. 1joule/s=1watt. ENERGY. The capability of doing work is called energy.
