How can different types of friction be helpful to humans?
friction is generated in the filament of a bulb when an electric current travels through it which creates heat and in turn light for us to use
parachutes can utilise air resistance to stop skydivers hitting the ground at high speeds by slowing them down
leaving a car window on the motorway can create increased drag and in turn use more petrol
pushing the brakes on a vehicle causes it to slow down
friction generated on a bike chain can make it harder to pedal
How are pulleys useful to humans?
they can be used to make a small force lift a lighter load
they can be used to reduce water resistance
they can be used to reduce air resistance
The more wheels in a pulley, the (a) force required to lift a weight.
