Front

What is speed?

Back

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

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

Back

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

Front

If a car travels 100 kilometers in 2 hours, what is its speed?

Back

Speed = 100 km ÷ 2 h = 50 km/h.

Front

What is average speed?

Back

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

Front

What is instantaneous speed?

Back

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

Front

What two measurements are necessary for calculating speed?

Back

Distance and time.

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 the formula for average speed when multiple distances are involved?

Back

Average Speed = Total Distance ÷ Total Time.
