Joule
The SI unit of work and energy (1N/1m)
Area under force v. Displacement is
Work
Energy
The ability of a system to to produce change in itself or in the world around it
Work-energy theorem
States that when work is done on a system , a change in energy occurs
Kinetic energy
The energy of an system that is associated with its motion
Power
the rate at which energy is transformed
Watt
Unit of power
Time and power
Work inversely
Work
The transfer of energy that occurs when a force is applied through a distance. Equal to the product of the systems displacement and the force applied to the system in the direction of displacement
Potential energy
Stored energy due to the interactions between objects in a system
Gravitational potential energy
The stored energy resulting from the gravitational force between objects represented by GPE
Reference level
Position where GPE is defined as zero
Elastic potential energy
Stored energy due to objects change in shape
Law of conservation of energy
States that in a closed isolated system energy is not created nor destroyed only conserved
Mechanical energy
The sum of kinetic energy and potential energy of the objects in a system me=ke+pe
