Push or pull on an object
Newton's Second Law of Motion
The net force acting on an object causes the object to accelerate in the direction of the force.
The force that opposes motion between two surfaces that are touching each other
responsible for the friction
Friction that forms between two surfaces that are not in motion
Friction that opposes the motion of two surfaces sliding past each other.
Friction between two surfaces rolling past each other.
- opposes downward motion
- a force that resists an object's motion
a place where no air is present
a speed where air resistance balances the pull of gravity
Law of Gravitation
Any two masses exert an attractive force on each other
Strong nuclear force
Weak nuclear force
the force that gives the universe its structure.
The gravitational force exerted on an object
Anything propelled through the air or space.
the rate of change of velocity
Acceleration along a curved surface or path.
Anything in around another body
