Mathematics of Motion
100
This is the starting point used to describe the location of an object.
What is the reference point?
100
This is measure of the distance an object travels per unit of time.
What is speed?
100
This is the speed and the direction of a moving object.
What is velocity?
100
This is the measure of the change in velocity during a period of time.
What is acceleration?
100
To get to the museum, you must pass the library and walk 120 meters. This is the reference position relative to the library.
What is +120m?
200
This is the object's distance and direction from a reference point.
What is position?
200
This is the unit of measure for speed.
What is meters per second (m/s)?
200
This is why the speed of a moving object does not completely describe its motion.
What is direction?
200
When the velocity of a car changes, this is what the car is actually doing.
What is accelerating?
200
On a baseball field, each base is 90 ft apart. This is the distance a baseball player runs after hitting a home-run.
What is 360 ft?
300
Direction includes the reference direction and the opposite direction. These two words are sometimes used to describe direction.
What is positive (+) and negative (-)?
300
This is the difference between constant and instantaneous speed.
What is distance?
300
These two factors will change velocity.
What is speed or direction?
300
An object accelerates when either its speed or its direction changes. (T/F)
What is true?
300
These are the three motions that can be shown on distance-time graphs.
What is slowing down, stopping, and speeding up?
400
This is the process of changing position.
What is motion?
400
This is the total distance traveled divided by the total time taken to travel that distance.
What is average speed?
400
This is how constant speed is shown on a distance-time graph.
What is a straight line?
400
This is the equation to find Acceleration.
What is final speed minus initial speed divided by total time?
400

Aidan drops a rock from a cliff. After 4.0 s, the rock is moving at 39.2 m/s. Using Vf-Vi/t, This is the acceleration of the rock.

What is 9.8 m/s2?

500
This is the difference between the initial (first) position and the final position of an object.
What is displacement?
500
This is how you'd calculate average speed.
What is divide total distance by total time (d/t)?

... v = d/t

500
After throwing a ball, it bounces. The change in this is the reason the ball does not have the same velocity at any position it is in.
What is the change in direction? or What is the change in speed?
500
On a graph, this visually represents when speed is constant.
What is a straight line?
500
When describing motion, this is one weakness of both a distance-time graph and a speed-time graph.
What is neither show changes in direction?
