Newton's 2nd 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
friction
force that opposes the sliding motion between two touching surfaces
static friction
frictional force that prevents two surfaces from sliding past each other
sliding friction
Frictional force that opposes the motion of two surfaces sliding past each other
air resistance
opposes the motion of objects that move through the air
gravity
attractive force between two objects that depends on the masses of the objects and the distance between them
weight
GRAVITATIONAL FORCE EXERTED ON AN OBJECT
centripetal acceleration
acceleration toward the center of a curved or circular path
centripetal force
net force exerted toward the center of a curved path
Newtons 3rd Law of motion
for every action there is an equal and opposite reaction
momentum
mass x velocity
the property of a moving object that equals its mass times its velocity
