Make sure you keep the Friction simulation open while you are working on these questions!
Question 1
1.
Use a complete sentence to explain how FRICTION affects how far the different objects moved.
Question 2
2.
Reset the simulation by clicking the orange arrow and then add an object, start pushing on the object but don't make it move.
Before the object starts to move the FRICTION force and the APPLIED force are _________
Balanced
Unbalanced
Question 3
3.
Reset the simulation by clicking the orange arrow and then add an object, start pushing on the object until it starts to move
After the object starts to move the FRICTION force and the APPLIED force are _________
Balanced
Unbalanced
Friction Experiment 1
Place a 50 Kg box on the ground, check all the boxes and answer the questions
Question 4
4.
Use a complete sentence to predict how much force it will take to move the box.
Question 5
5.
Use a complete sentence to explain what the actual force that moved the box was.
Friction Experiment 2
Place another 50 Kg box on top of the first box, check all the boxes and answer the questions
Question 6
6.
Use a complete sentence to predict how much force it will take to move the boxes.
Question 7
7.
Use a complete sentence to explain what the actual force that moved the boxes was.
Friction Experiment 3
Add one box to the ground, check all the boxes. Answer the question below
Question 8
8.
What happened to the force required to move the box when you increased the friction? (Move the friction slider to the right)
It stayed the same
It went up
It went down
Question 9
9.
What happened to the force required to move the box when you decreased the friction? (Move the friction slider to the right)
It stayed the same
It went up
It went down
Reflect on what you learned
Use complete sentences to answer these questions.
Question 10
10.
Friction affects how much force it takes to move an object
True
False
Question 11
11.
To make an object move the forces had to be unbalanced. Compare the FRICTION force to the APPLIED force when an object is moving.
