Acceleration ~ The rate of change of velocity of an object measured as a=vf-vi/t.
Velocity~ The rate of change of the displacement of an object.
Force~ a push or a pull of an object that causes the object to change its motion.
Force of friction~ a force that resists the motion of an object.
Impulse~ measured as the product of the force acting on an object and the times
which the force acts.
Momentum~ measured as the product of an object's velocity and mass.
Inertia~ the natural tendency of an object continue in the motion that it is going in
or stay at rest without a force acting on it.
Net Force~ the sum of all the forces acting on an object with direction.
Speed~ measured as the distance an object travels divided by the time it took to to travel
that distance. The direction does not matter with speed as it does with velocity because speed is a scaler (magnitude only
taken into account) while velocity is a vector (magnitude and direction taken into account).
Static frictional force~ the frictional force that keeps an object at rest that is measured
as the force to start an object moving.
Kinetic frictional force~the frictional force that acts on an object as it is moving at a
constant velocity; measured as the force to keep on object moving over another object.
Coefficent of friction~ the ratio of the frictional force to the normal force between two
objects rubbing surfaces.
Mass~ The mass of an object is not dependent on the force of gravity therefore the mass of
an object is different from but proportional to the object's weight.
Normal force~ the force that acts opposite the force of gravity and perpendicular to the direction
in which the object is a rest or in motion.
Stopping force~The force to stop an objects motion.
