Term | Definition |
---|---|
Air Resistance | Friction associated with the interaction of an object with the air |
Coefficient of Friction | The quantity that expresses the frictional forces between two objects |
Equilibrium | The point at which an object is at rest or moving with a constant velocity |
Force | A push or a pull |
Friction | the force that opposes movement between touching surfaces and always acts against the direction of motion. |
Inertia | matter's resistance to change in motion |
Kinetic Friction | The retarding force that acts upon a moving object in the opposite direction |
Momentum | The product of mass and velocity |
Net Force | The sum of all forces acting upon an object |
Newton's First Law | An object at rest remains at rest, and an object remains in motion unless acted upon by an outside force |
Newton's Second Law | The force an object exerts is equal to the object's mass multiplied by the object's acceleration |
Newton's Third Law | For every action there is an equal and opposite reaction |
Normal Force | A force acting in the opposite direction of another force |
Rolling Friction | Friction associated with one object rolling over another |
Sliding Friction | Friction associated with one object sliding over another |
Static Friction | The force opposing the movement of an object across a surface |
Weight | An objects mass multiplied by the gravitational force acting upon it |
