none of them are the least helpful
they all help things move upward except the lever
but the most helpful one is the pulley
a pulley takes up less space and it goes straight up so u can use less force
The inclined plane lessens the amount of force you need to lift an object like the other simple machine, the pulley but moves the object in a slant motion instead of the up and down motion of the pulley,
It is an inclined plane and some sort of pulley

No. A pulley is a simple machine in its own right.
No, that's one of the other simple machines.

Inclined plane. Otherwise known as a wedge.

A movable pulley. Kind of anticlimactic, isn't it?A pulley that is attached to something that isn't moving is called a fixed pulley.

If someone needs to use a pulley system to move or pull an object, there are a few important questions to ask about the pulley system. It is important to know, how much force the pulley system can withstand, and if the straps on the pulley system can secure the object you are moving.

Movable pulley is attache to the object you are moving while Fixed Pulley changes direction of the applied force.LaDy_caRoLi "Christine carren alcantara"
