Answer 4

Input- force applied by bikers feet to pedals
Process- the chain turns the gear system converting energy produced to cause
Output- the wheels turn and the bike moves

Question 5

If a cyclist is pushing 150 ways of power when cycling uphill, is this the same as on flat ground ?

Answer 5

Yes power is the same Jo matter the gradient however 150w uphill feels harder and as such the speed of travel can change and less distance will be covered due to gravity force
