centripital a force that causes an object to move in a circle
rolling friction that occurs when an object rolls over a surface
newton the S1 unit used for magnitude, or strength, of a force
force a push or pull exerted on an object
static friction that acts on objects that are not moving.
compression an elastic force that squeezes or pushes the molecules in matter together.
balanced forces equal forces acting on an object in opposite directions
mass a measure of how much matter is in a object
free fall the motion of a falling object when the only force acting on it is gravity
projectile an object that is thrown
net force the overall force on an object when all the individual forces acting on it are added together.
law of conservation of momentum the rule that in the absence of outside forces the total momentum of objects that interact does not change
tension an elastic force that stretches or pulls on the molecules in matter
sliding friction friction that occurs when one solid surface slides over another
unbalanced force forces that causes an object's velocity to cahnge
air resistance the fluid friction experienced by objects falling through the air
friction force that two surfaces exert on each other when rub together
fluid friction solid object goes through a fluid
gravity force that pulls objects toward each other
weight measure of gravity on object or person
inertia tendency of an object to resist change in motion
momentum characteristic of a moving object
satellite any object that orbits around another object in space
