100
This is the background assumed to be stationary when describing motion.
What is frame of reference?
100
This is the difference between speed and velocity.
What is velocity has a direction?
100
This is the formula for acceleration.
What is change in velocity divided by time?
100
This is the shape of a distance-time graph when velocity is constant.
What is a straight line.
100
A roller coaster at the top of a hill has a speed of 4 m/s. 3 seconds later, its speed is 22 m/s. What is its acceleration?
What is 6 m/s/s?
200
This is the most common frame of reference.
What is the Earth?
200
These are units used to measure speed.
What is any length per time unit?
200
This is what happens when acceleration is negative.
What is the velocity decreases?
200
This is the part of a distance-time graph that shows velocity.
What is the slope, or steepness?
200
You drive 40 km in 2 hours, then 60 km in 2 more hours. What is your average speed?
What is 25 km/hr?
300
A ball rolls down the aisle of a train. What is the frame of reference?
What is the train?
300
This is how to measure average velocity.
What is divide the total distance by the total time?
300
This is the shape of a distance-time graph when there is acceleration.
What is a curve?
300
A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard's acceleration?
What is 2 m/s/s?
400
You watch trees move past your window as your car drives down the highway. What is the frame of reference?
What is the car.
400
This is speed at one particular moment in time.
What is instantaneous speed?
400
A bicyclist goes from a complete stop to 8 m/s in 4 seconds. What is its acceleration?
What is 2 m/s/s?
400
That is how you calculate average speed from a distance-time graph.
What is measure the total distance, then the total time and divide the distance by the time?
400
A car travels 75 km north in three hours. What is its average velocity?
What is 25 km/hr north?
500
You watch the constellations slowly move across the sky at night. What is the frame of reference?
What is Earth?
500
This is the distance an object moving at 10 m/s travels in 10 seconds.
What is 100 meters?
500
A car has an acceleration over 10 seconds of -3 m/s/s. What is its change in velocity?
What is -30 m/s?
500
This is a possible story to goes along with this distance-time graph.
What are many possibilities?
