1. Carrying a Load

2. Remember… Force: any push or pull on an object
Friction: force that resists motion between two touching surfaces, slows things down and can also produce heat, acts in the opposite direction of the force
Inertia: the tendency of an object to resist a change in motion or keep doing what it is doing

3. Let’s Talk About Blocks!
Show two blocks of wood and ask students how the vehicle could be adapted to carry this load.

4. In your group:
You will use the falling weight system we looked at yesterday to move your vehicles.
We need to compare the difference in weight that it takes to pull your added force.

5. Think about this… What did you observe when testing the various loads?
How did the vehicle move when it was loaded with two blocks? One block?
What do you think would happen if you added a third or fourth block?
What can you conclude about the effects of a load on a vehicle’s motion?
