A push or pull that changes the way an object moves
Force
Define Newton's First Law
An object at rest stays at rest and an object in motion stays in motion, unless acted upon by an unbalanced force
An object will move in the _______ direction as the force applied to it.
Same
Define Newton's Third Law of Motion
For every action, there is an equal and opposite reaction.
What describes how fast or slow an object can move?
Speed
When an object is forced into motion, its ________ changes.
Position
If an object is at rest, it will stay at rest unless acted upon by an _____________?
Unbalanced force
Define Newton's Second Law of Motion
The acceleration of an object depends on the mass of the object and the amount of force applied.
Forces act in _____.
Pairs
The change of position (place) is also called _____?
(not motion or movement)
Displacement
When an object is not moving, the forces are _______?
Balanced
Gravity
The more force acted upon an object, the faster the ________.
Acceleration (speed)
When a force acts in one direction, it creates a force in the ________ direction.
Opposite
To speed up a moving object in a positive (forward) direction is called?
(starts with an "A")
Acceleration
A force can act as either a _____ or _______.
Push or Pull

Discovered
A force can change the speed (acceleration) and _______ of an object in motion.
Direction
If the fire and hot gas shooting out of a rocket is shooting downward, the rocket will go moving ______.
Upward
Velocity is the speed and ______ of an object.
Direction
When an object is in motion, the forces are ________.
Unbalanced
If an object is floating into space, what will happen if no force acts on it?
It will continue to float
A bowling ball because it has more mass
Anything you push or pull will always be ____ and ____ back on you.
Pushing and Pulling
Does mass change depending where you are? (Earth vs. Moon)
No it does not change
(Weight is different because it depends on gravity)
