Question

Which statements describe how a machine can help make work easier? Check all that apply.

It can put out more force than the input force by decreasing the distance through which force is applied.
It can increase the amount of work performed if the output force is in the same direction as the input force.
It can apply a force to an object in a different direction than the force applied to the machine.
It can increase the distance through which a force acts by exerting less force than was used on it.
It can exert a greater force through a greater distance than the force used on the machine.

Answer 1

The Answer Is C.

A machine helps to multiply force input and makes it easier to do work. Simple and complex machines are needed to make work easier.

₋ Most machines are designed to increase the input force by a system of mechanics.

- Machines allow force to be applied over great distances and this allows for the input work done to be duly compensated for.

Answer 2

It can increase the
distance through which the force acts by exerting less force than was used on it.
Work done = Force * Distance
when distance increase, less force is needed (by referring to the formula) thus work done will be easier and less effort (force) is needed
