forces acting in EQUAL and OPPOSITE directions. Creating NO MOTION.
balanced force
gaining or increasing speed
acceleration
The amount of distance something goes in a time period
speed
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)
the course something moves along.
direction
force that slows down an object that is rubbing on a surface
friction
Anything that has mass and takes up space
matter
The amount of space between 2 objects.
distance
A push or pull on an object
force
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
The strength of something when it is moving.
Momentum
A type of friction that slows objects down in the air.
air resistance
The location of an object.
position
The greater the _____ of an object, the more force it will take to accelerate the object.
mass
A force that pulls an object towards another object.
gravity
