How does a object that is not moving look on a motion detector?
100
An object in motion stays in motion and an object at rest stays at rest, unless acted on by an outside force.
What is Newton's first law?
100

What does FBD stand for?
200
grams
Typical unit used in Physics to measure mass
200
When your line on your graph is steadily inclining
What does walking backwards look like on a motion detector
200
Newton
What is the unit of force?
200
acceleration
Increase in speed is called this.
300
Vector
Velocity is this kind of force.
300
air pressure
What kept the hovercraft "floating" even though there was gravity pulling on them.
300
When your line on your graph is steadily declining
What does walking forward look like on a motion detector?
300
Inertia
Ojbects resist change in motion because they have ...what?
300
distance / time
Unit of velocity?
400
Forces acting on a single object are identical and acting in opposite directions
What are Balanced Forces
400
To mark up or adjust so something can be measured accurately
What is Calibrate
400
When your line on your graph quickly inclines
What is Accelerating quickly backwards in front of a Motion Detector
400
Increased mass causes increased inertia
How is an object's mass related to it's inertia?
400
Velocity has both magnitude and direction.
What is the difference between velocity and speed?

surface area
A paper plate has more of this, which allows it to "catch" more air pressure.
