1 11A 2.1c / 100 [T] Name: Part III - Friction's Effects The behavior of the skateboard in Part I and part II were not very realistic because friction was not present. At the bottom of the screen is a simulation that includes friction. Select this simulation. a. Set friction to "none". Notice how the screen changed. Why do you think the app designers did that? b. Make sure that only Speed box is checked. i. Apply a force to get the box to about half of it's maximum speed, then remove the force. ii. While the box is moving, move the friction slider to 1/2 way. What happened to the box? Summary Is friction a force? What evidence do you have have
