Speed is:
What is the measure of the distance an object travels per unit of time?
GPS means:
What is Global Positioning System?
Acceleration is:
What is a measure of the change in velocity during a period of time?
It takes Ahmed 50s on his bicycle to reach his friend's house 250 m away. What is his average speed?
What is 5 m/s?
This is an object's distance and direction from a reference point.
What is position?
What is the speed and direction of a moving object?
Name the four cardinal directions.
What are North, South, East and West?
When a car slows down, it is accelerating. True or false?
What is true? (Because acceleration is a measure of how the velocity of an object changes.)
Melissa has to go 400 miles. Her car can maintain an average speed of 50 mph. How long will it take her to reach her destination?
This is the starting point you choose to describe the location, or position, of an object.
What is reference point?
How can velocity change?
Velocity changes when speed or direction changes or when BOTH speed and direction change.
When are distance and displacement the same?
What is when an object moves in a straight line in one direction?
Name three ways an object can accelerate.
What are speed up, slow down or change direction?
Charles walks 1.5 m/s to the left. Eliza walks 1.5 m/s to the right. They are walking the same speed, but in different directions. What is this an example of?
What is velocity?
Displacement is:
What is the difference between the initial (first) position and the final position of an object?
These can be used to compare the motion of two different objects.
What are Distance-Time graphs?
Name two reference directions you might use to describe the position of a building in a city.
What is left, right, ahead, behind, North, South, East, West, etc.?
How is constant speed shown on a speed-time graph?
It is shown as a straight, horizontal line with a constant steady value.
If a car is traveling at 12 m/s, how long will it take the car to travel 144 m?
Tell me what motion is.
What is the process of changing position?
This is the formula for speed.
This is used to describe an object in two dimensions.
This is how a roller coaster can accelerate, even when it is moving at a constant speed.
What is change direction?
A bicyclist started from rest along a straight path. After 2.0s, his speed was 2.0 m/s. After 5 seconds, his speed was 8.0 m/s. What was his acceleration during the time from 2.0 to 5.0 s?
What is 2.0 m/22?
This is the total distance traveled divided by the total time taken to travel that distance.
What is Average Speed?
