11. The frictional force does depend on the contact/normal force (between the two objects that slip). So we need to be able to calculate or at least understand how to find the contact force. Give an example (not one from the lab or CYU), that uses friction, when a. the normal force equals the weight force b. the normal force is different than the weight force Explain what is different about those two situations and how you would go about finding the normal force. 11.
