Speed and Velocity

Front

What is speed?

Back

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

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Front

How do you calculate speed?

Back

Speed is calculated using the formula: S = d/t, where S is speed, d is distance, and t is 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 car travels 90 miles in 2 hours, what is its speed?

Back

The speed is 45 mi/hr.

Front

A runner completes a 100 meter race in 10 seconds. What is her average speed?

Back

Her average speed is 10 m/s.

Front

What two measurements are necessary to calculate speed?

Back

Distance and time are necessary to calculate speed.

Front

If a cyclist travels 30 kilometers in 1.5 hours, what is their speed?

Back

The speed is 20 km/h.

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 calculating average speed?

Back

Average speed = Total distance / Total time.
