1)How do pulleys make it easier to lift and object?
If you add more rope to pull it then it makes it easier to pull.
2)How do pulleys and levers work?
There is a circular thing with a rope around it and something is attached to one end and you pull on the other end to pull the load up.
3)What is the difference between a pulley and lever?
A pulley is when you pull to make something move and a lever is when you push to make something move.
The science experiment was fun.

1. A pulley system makes it easier to lift an object than lifting the dead weight by hand.

2. As the fulcrum at the centre of the wheel turns, the outer edge turns, extending the distance of the lever, and magnifying the force used.

I had Fun in science 🧪 in table 4 (purple) we got 300g.

To make pulleys easier you put a string on the lifting thing where you lift stuff and that is how you to lift a object easier.
Pulleys and levers pulleys are when you lift a object with some string and lift the object a lever.
A difference of a pulley and lever a pulley is different because it is where you lift it easier and a lever is also difference aswell.

1. Pulleys make things easier by using less strength.
2. Pulleys work by pulling a rope to lift objects and levers work by using effort to lift the load up.
3. The difference between a pulley and a lever is you use a rope to use a pulley but for a lever you use effort.

1.It made it easier because the wheel did the work and you had to pull the string
2.A lever is something that lifts heavy objects and pulleys is a wheel that can lift anything or pull
3.A lever you use force but a pulley is something you pull

Pulleys make it easier to lift things because you don’t have to hold it and you can get it higher and it’s easier.
Pulleys and levers work by the forces.
The difference between a pulley and a lever is that they are in different classes of forces.

How do pulleys make it easier to lift and object?
If you had more pulleys it will be easier but you have to do it more times the amount of pulleys you have
How do pulleys and levers work?
Levers help to push and pull something up and pulleys are used to do the same but easier

That pulleys are easier to use

Pulley is working by us pushing and pulling it so it works for us .
I had a fun time . I

How do pulleys make it easier to lift an object?
Pulleys make it easier to lift an object by the string. The more the string, the easier it will be to lift.
How do pulleys and levers work?
You use the string of the pulley to lift the load up and you use the effort of the lever to lift the load.
What is the difference between a pulley and lever?
When you use a lever, you use the effort to lift the load up but when you use a pulley, you use the string to lift the load up.
