Work
A measure of the energy transfer occurring when an external force moves an object over a distance.
Power
The rate at which work is done, calculated as work divided by the change in time.
Energy
The capacity to do work; can exist in kinetic, potential, or strain forms.
Work-Energy Relationship
The principle stating that work done on an object results in a change in its energy.
Kinetic Energy (KE)
Energy possessed by an object due to its motion, quantified as KE = ½ mass × velocity².
Potential Energy (PE)
Energy stored in an object due to its position relative to a reference point, particularly its height.
Strain Energy
Potential energy stored in an object as a result of deformation, calculated as Strain Energy = ½ k ΔX².
Mechanical Energy
The sum of kinetic and potential energy in a system; the energy due to its motion and position.
Positive Work
Work that adds energy to a system, occurring when the displacement is in the same direction as the force.
Negative Work
Work that removes energy from a system, occurring when the displacement is in the direction opposite to the force.
