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