FORCES AND FRICTION.

Lesson 4: What is friction?. Period 1 the amount resistance between two objects it happens when two objects rub together can create heat when you rub.

Whenever things are rolling over the ground, they stop after moving sometime. Give me another instance when on its own an object stopped moving. Carrom.

Friction What factors determine the strength of the friction force between two surfaces?

Friction A force that opposes motion. It occurs whenever 2 surfaces rub against each other. Friction occurs in our everyday life.

What Causes Friction? Even though a surface may look smooth, if you magnify the surface, you’ll see it isn’t smooth at all. Everything is made of molecules.

Friction Friction can be both good and bad. Advantages – my food stays on the silverware; falling off the side of a building; throwing a football Disadvantages = car engine parts sticking together; Slip-n-Slide; ice skating, bike or roller blades When friction is high, the surface is rough and bumpy. When friction is low, the surface is smooth. When two objects are rubbed together, energy is released in the form of heat and sound.
