The Moving Man Phet

Front

What is constant speed?

Back

Constant speed means moving at the same distance over equal intervals of time. For example, if a car travels 60 meters every 3 seconds, it is moving at a constant speed.

Front

What does it mean to accelerate?

Back

To accelerate means to increase speed over time. For example, if a runner starts slow and gradually runs faster, they are accelerating.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It gives an overall speed for the entire journey.

Front

What is a head start?

Back

A head start is when one runner begins the race before the others, giving them an advantage.

Front

What does a stationary object mean?

Back

A stationary object is one that is not moving. For example, a parked car is stationary.

Front

What is the difference between speed and velocity?

Back

Speed is how fast something is moving, while velocity includes both speed and direction. For example, 10 m/s north is a velocity.

Front

What does a graph showing constant speed look like?

Back

A graph showing constant speed is a straight line that slopes upwards, indicating equal distance covered over equal time.

Front

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

Back

The slope of a distance-time graph represents speed. A steeper slope indicates a faster speed.

Front

What does it mean when an object is returning to the start position?

Back

When an object returns to the start position, it means it has moved away from the starting point and then come back to it.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.
