energy

100

 force that results from the interaction of two objects in contact with each other

contact force

100

the use of force to move an object a certain distance

work

100

the energy an object has because it is moving

kinetic energy 

200

the speed and direction of an object

velocity

200

a push or pull

force

200

the energy that is stored inside an object

potential energy

200

the movement of energy from one object to another or the change of energy from one form to another

energy transfer

300

a force between surfaces that slows objects or stops them from moving

friction

300

force that occurs without objects touching

non-contact force

300

the combination of potential energy and kinetic energy
