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


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


attractive force between two objects that depends on the masses of the objects and the distance between them



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


mass x velocity
the property of a moving object that equals its mass times its velocity
