Newtons 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 can be calculated
|
|
|
friction
|
the force that opposes the sliding motion of 2 surfaces that are touching each other
|
|
|
static friction
|
the frictional force that prevents 2 surfaces from sliding past each other
|
|
|
sliding friction
|
the force that opposes the motion of 2 surfaces sliding past each other then forming again as the box slides along the floor
|
|
|
air resistance
|
opposes the motion of objects that move through the air
|
|
|
gravity
|
an attractive force between any two objects that depends on the masses of the objects and the distance between them
|
|
|
weight
|
the gravitational force exerted on an object
|
|
|
centripetal acceleration
|
acceleration toward the center of a curved or circular path
|
|
|
centripetal force
|
the net force exerted toward the center of a curved path
|
|
|
Newtons third law of motion
|
describes action-reaction pairs this way: When one object exerts a force on a second object, the second one exerts a force on the first that is equal in strength and opposite in direction
|
|
|
momentum
|
the product of its mass and velocity
|
