Thinking About It

In this activity, GEARBOT is programmed to move for 3 seconds then stop.

To push a load, GEARBOT exerts a force—the heavier the load, the greater the force.

Look at your graph to help you think about the following questions.

1. How does the distance change as the load increases?

2. How does the speed change as the load increases? How come?
