a push or pull

net force

the sum of all the forces acting on an object

inertia

the tendency of an object to resist changes in motion or position

Newton's first law of motion

states that the velocity of an object will remain unchanged unless an unbalanced force acts on it

mass

the amount of matter that makes up an object

friction

a force that acts between two surfaces in contact with each other and that tends to oppose motion

acceleration

the rate of change in an object's velocity

Newton's second law of motion

states that when a net force acts on an object, the object will accelerate in the direction of the net force

Newton's third law of motion

states that when one object exerts a force on a second object, the second object exerts a force on the first that is equal in size and opposite in direction
