Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is velocity?

Back

Velocity is speed with a direction.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

If a car travels 150 km in 3 hours, what is its average speed?

Back

50 km/h

Front

What is the difference between distance and displacement?

Back

Distance is how much ground an object has covered, while displacement is the shortest path from the initial to the final position.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

If a runner completes a 400 m lap in 50 seconds, what is their speed?

Back

8 m/s

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

If a car increases its speed from 20 m/s to 30 m/s in 5 seconds, what is its acceleration?

Back

2 m/s²

Front

What is a graph of speed vs. time used for?

Back

It shows how speed changes over time.
