Carrying a Load. 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

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