Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the formula for distance?

Back

Distance = Speed × Time.

Front

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

Back

A flat line indicates that the object is at rest (not moving).

Front

What does a straight diagonal line on a distance-time graph indicate?

Back

A straight diagonal line indicates constant speed.

Front

What does a curve on a distance-time graph represent?

Back

A curve indicates changing speed (acceleration or deceleration).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit time. It can be positive (speeding up) or negative (slowing down).

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does zero acceleration mean?

Back

Zero acceleration means the object is moving at a constant velocity.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope represents the speed of the object; a steeper slope indicates a higher speed.
