motion an objects change in position relative to a reference point
speed the distance traveled divided by the time interval during which the motion occurred
velocity the speed of an object in a particular direction
acceleration the rate at which velocity changes over time
force a push or a pull exerted on an object in order to change the motion of the object
newton the SI unit for force
net force the combination of all of the forces acting on an object
friction a force that opposes motion between two surfaces that are in contact
gravity a force of attraction between objects that is due to their masses
weight a measure of the gravitational force exerted on an object
mass a measure of the amount of matter in an object
terminal velocity the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
free fall the motion of a body when only the force of gravity is acting on the body
projectile motion the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth
inertia the tendency of an object to resist a change in motion unless an outside force acts on the object
