efficiency
the ratio of output work to input work
mechanical advantage
the ratio of the output force to the input force
energy
the ability to cause change
kinetic energy
energy due to motion
potential energy
energy that is stored due to the interactions between objects
elastic potential energy
energy that is stored by compressing or stretching an object
gravitational potential energy
energy that is due to the gravitational forces between objects
law of conservation of energy
states that energy cannot be created or destroyed. Energy can only be converted from one form to another or transferred from one place to another.
mechanical energy
the sum of the kinetic energy and the potential energy of the objects in a system
power
the rate at which energy is converted
wave
a repeating disturbance that transfers energy through matter or space
transverse wave
where particles in the medium moves back and forth at right angles to the direction that the wave travels
longitudinal wave
where matter in the medium moves back and forth along the same direction that the wave travels
