Understand Friction
Friction - the force - acts all around us whenever surfaces rub together.
Friction can be useful, and it can also be very unhelpful.
Smooth surfaces and streamlined shapes reduce friction.
Rough surfaces and lumpy, awkward shapes increases friction.
Increasing the area of the surfaces which rub together also increases the size of the force.
In this worksheet you will be asked some questions on friction, let's see what you can remember!
