  1. When two surfaces rub together, the irregularities of one surface Friction The force that one surface exerts on another Friction acts in a direction

  2. Friction Without friction, the object would continue to move at The strength of the force of friction depends on two factors:

  3. When two surfaces rub together, the irregularities of one surface Friction get caught on those of the other surface. The force that one surface exerts on another when the two rub against each other is called Friction. Friction acts in a direction opposite to the object’s direction of motion.

  4. Friction Without friction, the object would continue to move at constant speed. The strength of the force of friction depends on two factors: • the type of surfaces involved and • how hard the surfaces push together.

  5. Different Types of Friction __________ Friction – when solid surfaces slide over each other. ( _____ Friction) __________ Friction – when an object rolls over a surface. (_____ Friction) _______ Friction – the friction that occurs when an object moves through a liquid or a gas. (______ Friction)

  6. Different Types of Friction A liquid or gas is commonly used to Lubricants change _______________ friction to ______________ friction.

  7. Different Types of Friction Sliding __________ Friction – when solid surfaces slide over each other. ( _____ Friction) Most Rolling __________ Friction – when an object rolls over a surface. (________ Friction) Some Fluid _______ Friction – the friction that occurs when an object moves through a liquid or a gas. (______ Friction) Least

  8. Different Types of Friction A liquid or gas is commonly used to reduce friction; they are known as- Lubricants. sliding Lubricants change ___________ friction to __________ friction. liquid
