Front

If a car travels 400 meters in 10 seconds, what is its speed?

Back

40 m/s.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Back

Newton (N).

Front

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

Back

It represents that the object is at rest.
