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 unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).

Front

If a runner completes a 400 m race in 100 seconds, what is their speed?

Back

Speed = 400 m / 100 s = 4 m/s.

Front

What is average speed?

Back

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

Front

If Bill jogs 400 meters to Andy's house and back in 267 seconds, what is his average speed?

Back

Average speed = Total distance / Total time = (400 m + 400 m) / 267 s ≈ 3 m/s.

Front

What is a unit of time?

Back

A unit of time is a standard measure used to quantify time, such as seconds (sec) or hours (hr).

Front

What does a speed of 0 m/s indicate?

Back

A speed of 0 m/s indicates that an object is at rest and not moving.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is a head start in a race?

Back

A head start is when one runner begins the race ahead of the others, giving them an advantage.
