Tension An elastic force that stretches or pulls on the molecules in matter.
Sliding Friction Friction that occurs when one solid surface slides over another.
Unbalanced Force Forces that cause an object's velocity to change.
Air Resistance The fluid friction experienced by objcets falling through the air.
Rolling Friction Friction that occurs when an object rolls over a surface.
Gravity The force that pulls objects toward each other.
Newton The SI unit used for magnitude, or strength, of a force.
Weight A measure of the force of gravity on an object.

Inertia The tendency of an object to resist any change in its motion.
Compression An elastic force that squeezes or pushes the molecules in matter together
Satellite Any object that orbits around another object in space.
Balanced Forces Equal forces action on an object in opposite directions.
Momentum The product of an object's mass and velocity.
Mass A measure of how much matter is in an object.
