Friction forces and terminal speed

Physics revision

  • Friction allows things to slow down.
  • Friction acts on a moving object. It acts in the opposite direction that the object is moving to.
  • Frictional force will match the size of the force trying to move it, up to a point. However after this, when the force is greater than the frictional force the object will move faster.
  • Friction makes objects slow down and stop.
  • A driving force will always be required to overcome friction in order to travel at a steady speed.

Static friction:

  • This is when friction between solid surfaces that are gripping to each other. This is also known as static friction.

Sliding friction: 

  • This is when there…
