###### PLAY
air resistance
force that opposes the motion of objects that move through the air
centripetal acceleration
acceleration of an object toward the center of a curved or circular path
centripetal force
a net force that is directed toward the center of a curved or circular path
friction
force that opposes the sliding motion between two touching sufaces
gravity
attractive force between two objects that depends on the masses of the objects and the distance between them
momentum
property of a moving object that equals its mass times its velocity
Newton's second law of motion
states that the acceleration of an object is in the same direction as the net force on the object, and that the acceleration equals the net force divided by the mass
Newton's third law of motion
states that when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and in the opposite direction
sliding friction
frictional force that opposes the motion of two surfaces sliding past each other
static friction
frictional force that prevents two surfaces from sliding past each other
weight
gravitational force exerted on an object
