| A | B |
| Position | the location of an object |
| momentum | the more momentum the easier it is to move other objects |
| force | units are the newton and pound |
| energy | the ability to do work |
| velocity | measurement that combines speed and direction |
| work | the amount of work changes the amount of energy |
| fulcrum | pivot point for a lever |
| friction | force that opposes the motion of one object moving past another |
| efficiency | high efficiency would be outputting most of the energy they use |
| law of conservation of energy | energy can't be created or distroyed |
| acceleration | change in velocity over time |
| balanced force | when 2 forces act on an object from opposite directions |
| potential energy | stored energy |
| simple machine | takes 1 force and changes it to another force |
| effort | the force applied to a machine |
| compound machine | when 2 or more machines are combined |
| kinetic energy | the energy of a moving object |
