1 Week 27 Warm UP pg 60-61 What is the difference between a balanced and an unbalanced force? Calculate the net force on these objects: Are the forces on the above objects balanced or unbalanced? Will the following object move? Which way? With how much force? 12 N15 N 38 N Object 1 Object 2 Object 3 7 N 4 N

2 Week 27 Warm UP pg 60-61 What is a force? What is the unit used for all forces? Why is a force considered a vector? What do you do with forces in the same direction? What do you do with forces in opposite directions?

3 Week 27 Warm UP pg 60-61 What is friction? What are two things you could do to increase friction? Give an example of something you could do to better explain one of the types of friction. Explain how your life would be different if friction did not exist.

4 Give a situation where you would want to increase the friction. Explain why you would want to increase the friction. What direction is friction always in? What are the different types of friction? Is gravity a force? What do you think causes gravity? Week 27 Warm UP pg 60-61
