A force that pulls an object towards another object.
gravity
the course something moves along.
direction
The amount of distance something goes in a time period
speed
For every action, there is an equal and opposite ________
reaction
2 or more forces where one force is stronger than the other. This results in the object moving.
unbalanced force
An object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force.
inertia (or Newton's 1st law of motion)
A type of friction that slows objects down in the air.
air resistance
Anything that has mass and takes up space
matter
A push or pull on an object
force
The greater the _____ of an object, the more force it will take to accelerate the object.
mass
The amount of space between 2 objects.
distance
The location of an object.
position
force that slows down an object that is rubbing on a surface
friction
The strength of something when it is moving.
Momentum
forces acting in EQUAL and OPPOSITE directions. Creating NO MOTION.
balanced force
gaining or increasing speed
acceleration
