Calculating Average Speed Practice

Front

What is average speed?

Back

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

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

What is the unit of speed?

Back

The unit of speed is typically meters per second (m/s) or kilometers per hour (km/h).

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

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time.

Front

What does a flat line on a speed-time graph indicate?

Back

A flat line indicates that the object is moving at a constant speed.

Front

What does a steeper slope on a distance-time graph indicate?

Back

A steeper slope indicates a higher speed.

Front

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

Back

Average speed = 100 km / 2 hours = 50 km/h.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity as it indicates the path along which an object is moving.
