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