Graphs
100
This is the starting point you choose to describe the location, or position, of an object.
What is a reference point?
100
This is the SI unit of speed.
What is meters/second (m/s)?
100

This symbol is used to represent the velocity of an object.

What is an arrow that points in the direction of the object's motion?

100

This is what most people incorrectly think acceleration means.

What is speeding up?

100
You can calculate the average speed of an object using this type of graph.
What is a Distance-Time graph?
200
This is the process of changing position.
What is motion?
200
This is the formula used to calculate average speed.
What is average speed = total distance divided by total time?
200
These are the two components of velocity.
What are speed and direction?
200
These are 3 ways an object can accelerate.
What are speeding up, slowing down, and changing direction?
200
This is what you see on a Distance-Time graph when an object stops moving for a period of time.
What is a horizontal line?
300
When finding the difference between the initial position and the final position of an object, you are finding this.
What is displacement?
300
This is the rate of change of position in which the same distance is traveled each second.
What is constant speed?
300
This is what the length of a velocity arrow represents.
What is the speed of the object?
300
This is the SI unit for acceleration.
What is m/s2?
300
This is the component seen on the x-axis of a Distance-Time or Speed-Time graph.
What is time?
400
A complete description of your position includes these three things.
What are distance, direction, and a reference point?
400
This is how constant speed is shown on a Distance-Time graph.
What is a straight line?
400
This is the velocity of a train moving south, traveling 350 kilometers in 2.5 hours.
What is 140 km/h south?
400
This is the formula used to calculate acceleration.
What is Acceleration = (final speed - initial speed)/total time?
400
This is how the slope of the line changes on a Distance-Time graph when the object slows down.
What is decreases?
500
When you move in this way, distance and displacement are equal.
What is moving in a straight line?
500
It takes Aaron 30 s on his bicycle to reach his friend's house 215 m away. This is his average speed in SI units.
What is 430 m/s?
500
These are the 3 ways that velocity can change.
What are a change in speed, a change in direction, and a change in both speed and direction.
500
This is the acceleration of a car traveling on a straight road whose speed increases from 63 m/s to 75 m/s in 4.2 s.
What is 2.9 m/s2?
500
This is what you see on a Speed-Time graph when the object's speed is constant.
What is a horizontal line?
