Calculating Average Speed

Front

Define average speed

Back

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

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time

Front

Define acceleration

Back

Change in speed or velocity over a specific period of time.

Front

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

Back

The object is at rest.

Front

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

Back

The object is moving quickly.

Front

What is the unit of speed?

Back

Meters per second (m/s) or kilometers per hour (km/h).

Front

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

Back

50 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 does it mean to accelerate?

Back

To increase the speed or change the direction of an object.

Front

If a driver travels 60 km in 1 hour and then 90 km in 2 hours, what is the average speed for the entire trip?

Back

50 km/h.
