Force and Motion

Niewoehner Science Review

Acceleration The rate at which the speed or direction of an object changes
Gravity The force of attraction between any two objects
Acceleration The measure of how quickly velocity changes
Contact Force A force that requires two pieces of matter to touch
Inertia The tendency of an object to resist a change in motion
Non-Contact Force A force that acts at a distance
Friction A force that opposes motion between objects that are touching
Air Resistance Type of friction used to slow a parachute
Newton's First Law States that an object will not move or change its direction unless it is acted upon by a force
Magnetism A type of non-contact force between metals
Force A push or pull that acts on an object
Large Masses Harder to accelerate
Newton's Second Law States that the acceleration of an object depends on the mass of the object and the net force applied
Smaller force Produces less acceleration
Net Force The combination of all the forces acting on the object
Newton's Third Law For every action force there is an equal and opposite reaction force
