The advantage a machine has over a bicycle

A measure of how much a simple machine reduces work

A measure of when is the best time to use a simple machine

the number of times a machine increases the input force

the force one exerts on a machine

the force which an effort force must overcome in order to do work on an object via a simple machine.

the force the machine exerts on a object

the output work times the input distance

the force required by a machine in order to accomplish work (the force you put on the machine)

The force that is exerted by a machine

the force the machine exerts on a object

the output work times the input distance

as distance increases, effort (INPUT FORCE) decreases

as distance decreases, effort (INPUT FORCE) decreases

as distance increases, effort (INPUT FORCE) increases

nothing, they both stay the same
