Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is calculated using the formula: Speed = Distance / Time.

Front

What information do you need to calculate speed?

Back

You need distance and time.

Front

If a runner travels 6 miles in one hour and 8 miles in the next hour, what can be said about her speed in the second hour?

Back

The runner is speeding up because she traveled a greater distance in the same amount of time.

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed x Time. This means that to find distance, you multiply speed by time.

Front

What two measurements are needed to determine an object's speed?

Back

Distance and time.

Front

If two cars travel the same distance but one arrives first, what can be concluded about their speeds?

Back

The car that arrived first traveled faster than the other car.

Front

What does it mean if an object is slowing down?

Back

It means that the object's speed is decreasing over time.

Front

What is the formula to find speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only, such as speed or distance.
