100
this is a push or a pull
What is a force
200
This is the force that always opposes motion

200
When an object changes speed or direction is expalin by _____
What is Newtons 2nd Law
200
The force that always acts in one direction
What is action force
200
What is the formula for finding Acceleration?
What is Acceleration = (Final speed - Initial speed)/Time
200
State the formula that relates to Newtons 2nd Law of Motion
What is F = M x A
300
When an object reaches a point where gravity is balanced with the force of air resistance (they are equal)
What is terminal velocity
300
This states that an object at rest will stay at rest or an object in motion will stay in motion until a net force acts on it.

What is mass
400
This is the upward force exerted by a fluid
What is buoyant force
400
This states that an object acted upon by a net force will accelerate in the direction of the force
What is Newtons 2nd Law
400
The force that always acts in the opposite direction
What is reaction force
400

What is 12.5 km/hr
400
all moving objects have this force, which will increase with speed
What is momentum
500
An objects tendency to resist motion or to stay in motion
What is inertia
500
States that reactions happen in pairs
What is Newtons 3rd Law
500
The force that acts exactly upward on an object and is equal to the objects gravitational pull
