Rolling Friction Friction t.hat occurs when an object rolls over a surface
Static Friction Friction acts on objects that are not moving.
Balanced Forces Equal forces acting on an object in opposite directions.
Free Fall The motion of falling object when the only force acting on it is gravity.
Mass A measure of how much matter is in an object.
Compression An elastic force that squeezes or pushes the molecules in matter together.
Force A push or pull exerted on an object.
Newton The SI unit used for the magnitude, or strength, of a force.
Centripetal Force A force that causes an object to move in a circle.
Net Force The overall for on an object when all the individual forces acting on it are added together.
Law of Conservation of Momentum The rule that in the absence of outside forces the total momentum of objects that interact does not change.
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 Forces Forces that cause an objects velocity to change.
Air Resistance The fluid friction experienced by objects falling through the air.
Gravity The forces that pulls objects toward each other.
Weight A measure of the force of gravity on an object.
Fluid Friction Friction that occurs as an object moves through a liquid or gas.
Inertia The tendency of an object that orbits around another object in space.
Satellite Any object that orbits around another object in space.
Momentum The product of an object's speed and velocity.
Friction The force that one surface exerts on another when the two surfaces rub against each other.
