A push or pull
to change position
The distance traveled over a certain period of time
a change in speed or direction
the speed of an object in a particular direction
a force of attraction between two objects depending on the mass of those objects.
a force that resists motion by way of contact between two things
a force that resists motion as two things slide across each other
resistance of motion caused by a round object rolling across another object
a force that resists motion of an object due to a liquid or gas
Unit used to measure a force (N).
Newton's Second Law
An object will accelerate, depending on the object's mass, and the forces exserted on the object.
Newton's Third Law
For every action force, there is an equal but opposite reaction force
Newton's First Law
In object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.
When two forces acting on each other cause an object to move.
When forces acting on each other equally and in opposite directions which cause no movement of an object
A measure of the motion of an object due to its mass and velocity.
The tendancy of an object to resist movement or a change in movement.
Two objects not in motion due to their contact
A fixed point that you may use to determine if something is moving.
