Chapter 10-2 Friction and Gravity

Friction Force of Friction – caused by two surfaces rubbing Strength: depends on 1) how hard the surfaces are pushed together 2) types of surfaces Direction: Opposite to direction of motion

Types of Friction Static Friction – friction that acts when an object is not moving. Need to overcome to START moving Sliding Friction – friction that acts when an object is moving Less than Static Friction Sliding Sliding Friction

Types of Friction Rolling Friction– friction that acts when an object rolls Less than Static Friction or Sliding Friction Fluid Friction – friction that acts between a solid and fluid(remember a gas is a fluid) Less than Static or Sliding
