what is a lever made of?

A lever is an object that is used with a pivot point, or 'fulcrum', to multiply the force applied to another object. Levers are often long and skinny and made of rigid material.

Why do pulleys make lifting easier?

Pulleys are powerful simple machines. They can change the direction of a force, which can make it much easier for us to move something. ... Pulleys can also provide us with a mechanical advantage when we use several together and more rope. This process lessens the amount of force required to lift something

How does inclined plane work?

An inclined plane makes it easier to raise something heavy, like a rock. ... Because work is force multiplied by distance, the amount of work remains mostly the same, In a steep ramp, it will be harder to push the rock/load but you won't need to push it as far.

Do wheels reduce friction?

No force is transferred or modified by a rotating wheel. Instead, a rotating wheel can make work easier by reducing the friction between an object and the surface over which it moves.
