Average Speed and Graphs

Front

What is average speed?

Back

Average speed is how much distance is covered over a period of time.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

If a car travels 120 km in 2 hours, what is its average speed?

Back

60 km/h.

Front

What does a speed-time graph represent?

Back

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

Front

What is a constant speed?

Back

Constant speed means the object covers equal distances in equal intervals of time.

Front

If a runner jogs at a speed of 8 km/h for 3 hours, how far do they go?

Back

Front

What is the unit of speed in the metric system?

Back

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

Front

What does it mean if a graph is a straight line?

Back

A straight line on a distance-time graph indicates constant speed.

Front

What is the speed of an object that travels 100 meters in 5 seconds?

Back

20 m/s.

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).
