Work is the product of the applied force (
) and the displacement (s) of an object, which is has the same direction as the force.
Work is considered as Negative and Positive
Work is considered positive if it is produce by a force which has the same direction as the direction of the displacement. Positive work can move non-moving object.
Work is considered negative, it is product by a force which has an opposite direction to the direction of the displacement
The conclusion for to do work
There is a force that causes displacement of the object
The direction of the force has to be the same as the direction of the displacement.
Energy is the ability to perform work
Forms Of Energy
Thermal energy is the energy associated with the microscopically random motion of particle constituting the substance.
Sound energy is the energy product through the vibration of air particles around a sound source.
Chemical energy is an energy contained within food, your body, and fuel (such as coal, oil, and natural gas).
Light energy is the energy product by the radiation of electromagnetic.
Electric energy is the energy product by electric charges which move through the cables.
Nuclear energy is the energy released from the reaction of the nucleus of radioactive matters.
Mechanical energy is the energy associated with the motion.
Potential energy is energy that is stored within an object.
Spring potential is energy exists because an object tends to maintain its initial position.
Gravitational Potential energy
Gravitational potential energy is the energy possessed by an object because of its position related to a certain frame of reference (for example, the floor and ground).
