Calculating Speed

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

How is speed measured?

Back

Speed can be measured in meters per second (m/s).

Front

What is the formula for average speed?

Back

Average speed = Total distance / Total time.

Front

If a runner covers 200 meters in 20 seconds, what is their average speed?

Back

10 m/s.

Front

What does it mean if a runner has a constant speed?

Back

It means the runner covers equal distances in equal intervals of time.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the difference between speed and velocity?

Back

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

Front

If a car travels 150 kilometers in 3 hours, what is its average speed?

Back

50 km/h.

Front

What is the unit of distance in the metric system?

Back

The unit of distance is meters (m).

Front

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

Back

Distance = Speed × Time.
