Chapter 5 Section 3 Friction: A Force That Opposes
... Friction: Harmful and Helpful • Without friction, a car’s tires could not push against the ground to move the car forward, and the brakes could not stop the car. Without friction, a car is useless. • However, friction can also cause problems in a car. Friction between moving engine parts increases t ...

... A 60.0-kg person running at an initial speed of 4.00 m/s jumps onto a 120-kg cart initially at rest (Figure below). The person slides on the cart’s top surface and finally comes to rest relative to the cart. The coefficient of kinetic friction between the person and the cart is 0.400. Friction betw ...

... Determine the amount of time required for the vehicle to slip back to the bottom of the hill, measured from the time the vehicle started up the hill. (hint: Unlike most problems of this type, the direction of the friction force doesn’t change when the vehicle changes direction! The tires are still s ...

It is now your chance to pull it all together by writing a well written, thoughtful paragraph about how the terms below are all interrelated. It should make logical sense and include all of the following terms. (Pl ...
