Work
The energy transferred to or from a system as a force acts on it through a displacement
Joule
The SI unit of energy and work (N x M = J)
Spring Constant
A value used in Hooke's Law with the units N/m
Equilibrium
The rest position of a system
Hooke's Law
A scientific law that states that within the elastic limit of a material, the restoring force is directly proportional to the displacement of the system from its equilibrium position
Ideal Spring
A hypothetical object that has no internal resistance, has no mass, and is perfectly elastic
Power
The time-rate at which work is performed
Watt
SI unit of power
Energy
The property of a system that gives it the ability to do work
Work-Energy Theorem
The work done on a system by all external forces is equal to the change in the system's kinetic energy
Potential Energy
Mechanical energy that objects possess because of position or condition
Conservative Force
A force that can convert kinetic energy to potential energy and vice versa without loss
Conservation of Mechanical Energy
A principle that applies to an ideal system that has no energy losses due to drag or friction
