What is a pulley, and why is it useful? Give an example! lolop https://padlet.com/lolop/HAHA/wish/156125202 A pulley is a simple machine that spreads the work and makes you pull the rope to lift the thing you put on the other side of the rope.

It's useful because it helps people lift stuff with less force.

An example of this is a crane because it uses a pulley to lift heavy objects.

They're useful because we use them to move our self and objects.

An example of them being used is a set of car wheels.

It's useful because it is sharp and we put the force on to the wide part and more force comes out of the sharp end and it breaks/cuts objects with less force.

An example of this is an a doer holder.

It's useful because when you cant bend your arm it's useless.(look at the example)

An example of this is your forearm.

Give an example! lolop https://padlet.com/lolop/HAHA/wish/156125207 An inclined plane is a ramp that makes moving things more easy by taking some of the weight and making you put less work than lifting your object.

It's useful because it makes you use less force.

An example of this is when people use ramps to put things on/in their car.
