300
An object moving at a constant rate of speed is moving in?
What is Uniform Motion
300
Which of Newton's laws states that for every action, there is an equal and opposite re-action?
What is Newton's third law
400
A car travels between 2 towns 60 miles apart in 2 hours. What is its average speed?
What is 30 miles/hour. (average speed = distance/time Therefore, the average speed of the car is 60 miles/2 hours = 30 miles/hour)
400
Which of the following could be a speed measurement? 2.5 meters 2.5 seconds/meter 2.5 meters/second 2.5 meters/second/second
What is 2.5 meters/second (. Speed always has units of a distance (length) unit divided by a time unit)
400
What are the two variations of Velocity?
What is Average velocity and Instantaneous velocity
400
An estimate to find average speed is called?
What is Line of Best Fit
400
The tendancy of an object to resist any change in it's motion is called?
What is Inertia
500
If a person can walk with an average speed of 2 meters/second, how far will they walk in 4 minutes?
What is 480 meters. (There are 60 seconds in 1 minute, so there are 4 (60 seconds) = 240 seconds in 4 minutes. Also, if average speed = distance/time, then distance = (average speed)(time). Therefore, the distance the person moves is (2 m/s)(240 s) = 480 meters)

Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.8 seconds, then what is the acceleration and what is the distance that the sled travels?
What is a = 247 m/s/s d = 400 m
