This is the measure of how fast something moves or the distance it moves.
What is speed?
100
The rate at which velocity changes with time is called this.
What is acceleration?
100
A runner covers 100 meters in 50 seconds. This is her speed.
What is 2 m/s?
200
This is the location to which you compare other locations.
What is a reference point?
200
You cannot tell what a person's ________ is by looking at them move.
What is speed?
200
This is the formula to figure speed.
What is distance divided by time?
200
If you are going 30 miles per hour, and you slow down, you are doing this.
What is accelerating?
200
A runner goes 50 meters in 15 seconds. This is his speed.
What is 3.33m/s?
300
This is the measure of distance in science.
What is a meter?
300
How you see things when you are in motion.
What is relative motion?
300
Speed is not constant, so you can use this because it is easier.
What is average speed?
300
This is what happens when you accelerate by going slower.
What is negative acceleration?
300
A sled is going down a snow-covered slope starting at a velocity of 1 m/s. After 3 seconds, the sled is going 7 m/s. This is the acceleration of the sled.
What is 2 m/s squared?
400
These are the two ways to measure distance between two places.
What are straight-line distance and actual distance?
400
This is the movement that is side to side.
What is horizontal?
400
These two things make up velocity.
What is speed and direction?
400
These two things are needed to calculate acceleration.
What is velocity and time?
400
A man walks at 0.5 m/s, then accelerates to a velocity of 0.6 m/s in 1 second. This is his acceleration.
What is 0.1 m/s squared?
500
This is the motion that goes up and down.
What is vertical?
500
This is an example of how the apparent motion of an object depends on the observer's motion.
What is ____________?
500
Velocity is an example of this.
What is a vector?
500
This is the formula to calculate acceleration.
What is acceleration = (final velocity - initial velocity) divided by time?
500
A train traveling at 10 m/s slows down to a complete stop in 20 seconds. This is the acceleration of the train.
