100
How far an object has moved
What is distance
100
This occurs when an object speeds up in its direction of motion
What is positive acceleration
100
This is the type of force when the net force on an object is zero
What is balanced force

Adrian Peterson ran 40 m in 4.5 s. What was his speed?
What is 8.8 m/s
100
This is the proper unit of acceleration
What is m/s squared
200
This is needed to determine the position of an object
What is a reference point
200
This is the rate of change of velocity
What is acceleration
200
This is the combination of all the forces acting on an object
What is net force
200
A car traveled 200 kilometers from Meridian to Vicksburg in 2.5 hours. What was its average velocity?
What is 80 km/h West
200
This is why a passenger who is not wearing a seat belt will likely hit the windshield in a head-on collision
What is inertia
300
This is the speed and direction of a moving object
What is velocity
300
This makes objects accelerate towards the ground
What is gravity
300
This is a push or a pull
What is a force
300
A motorcycle traveling south with a velocity of 30 m/s speeds up to a velocity of 80 m/s within 10 s. What is the motorcycle's acceleration?
What is 5 m/s squared
300
If you walked 50 m from your desk to your locker then back, what would be your distance and displacement?
What is Distance= 100m. Displacement= 0m
400
This is the distance and direction of an object's change in position from the starting point
What is displacement

Coach Raley's speed went from 55 mph to 35 mph when he entered Marion. This is an example of...
What is negative acceleration
400
This is the resistance of an object to a change in motion
What is inertia
400
A person wakling covers 5.20 m in 10.4 s. How fast is the person moving?
What is .5 m/s
400
This is the speed when you look at your speedometer
What is instantaneous speed
500
This is the equation used to calculate speed
What is speed=distance/time
500
This is the formula for calculating acceleration
What is A= final velocity-initial velocity/time
500
This is what Newton's First Law states
What is the motion of an object does not change unless an unbalanced net force acts on the object
500
A car goes from 16 m/s to 2 m/s in 3.5 s. What is the car's acceleration?
What is -4 m/s squared
500
A horizontal line on a distance-time graph means this...
What is the object is at rest
