Calculating Speed and Average Speed

Front

What is speed?

Back

Speed is a measurement of how fast an object is moving, typically expressed in units like meters per second (m/s) or kilometers per hour (km/h).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

If you run around a 2-mile football field 3 times, what is the total distance?

Back

6 miles.

Front

What is the average speed of a runner who completes a 100 meter dash in 10 seconds?

Back

10 m/s.

Front

If you walk 10 meters to class in 20 seconds, what is your average speed?

Back

0.5 m/s.

Front

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

Back

Distance = Speed x Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

If a car travels at an average speed of 110 km/h, how long will it take to travel 715 km?

Back

6.5 hours.

Front

What units are commonly used to measure speed?

Back

Common units for speed include meters per second (m/s) and kilometers per hour (km/h).

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction, such as speed.
