Net Force
a) The force that opposes motion.
b) Accelerates a 1kg mass 1 m/s per second.
c) The overall force acting on an object.
d) A force that acts between two masses.

Inertia
a) Is solely based on the mass of an object.
b) The tendency of an object to resist a change in its motion.
c) An object in motion, will stay in motion. An object at rest will stay at rest.
d) All of these are correct.

Weight
a) The force of gravity acting upon a mass.
b) The amount of mass something has.
c) Determines the amount of inertia within an object.
d) How heavy something is.

Newton's Second Law
