What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the formula to calculate time when distance and speed are known?

Back

Time = Distance / Speed.

Front

What is a hypothesis?

Back

A hypothesis is a testable explanation for a problem or observation that has not yet been tested.

Front

What is a dependent variable?

Back

The dependent variable is what is being measured in an experiment.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in an experiment.

Front

What is the average speed of an object?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

If a cheetah travels 112.0 m in 4.0 s, what is its speed?

Back

28.0 m/s.

Front

What units are commonly used to measure speed?

Back

Meters per second (m/s) or kilometers per hour (km/h).

Front

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

Back

Distance = Speed x Time.
