Inertia
The tendancy of an object to resist changes in its velocity.
Friction
A force that opposes motion, resulting from the contact of two surfaces.
Kinetic Friction
Friction that opposes motion once the motion has already started.
Static Friction
Friction thhat opposes the initiation of motion.
Newton's law of inertia
A object in motion (or at rest) will tend to stay in motion (or at rest) until it is acted upon by an outside force.
Newton's law of force
When an object is acted on by one or more outside forces, the total force is equal to the mass of the object times the resulting acceleration.
Newton's law of friction
For every action there is an equal and opposite reaction.
