Using a wheelbarrow can make it easier to lift a heavy object by?
Yes it does make it easier by using a fulcrum Yes it does make it easier by using a fulcrum
How does a ramp make it easier to move heavy objects?
What a ramp does is trade distance for height. So it's not easier to move an object so much as it's easier to lift an object with a ramp.
Is it easier to pull an object or lift it?
which requires more energy, pulling a load, lifting, or pushing a load?
How does an incline plane affect the work that is done on an object?
it reduces the work by making an object easier to carry or lift to a higher or lower ground
Why is it easier for two people to lift a heavy object than it is for one person to lift it on their own?
it isn't easy for one person because one person doesn't has much mass but when two people mass is added, so they can lift a heavy object
Why is it easier to lift an object that is underwater than it is to live the object whenit is out of the water?
the water provides a bouyant force proportional to the volume of water displaced.

What is one disadvantage of using pulleys?
A pulley uses leverage to displace the pressure of an object, making said object easier to lift
What is a pulley system?
It is a system of ropes and wheels that achieve the purpose of making an object easier to lift.
Does the use of an incline plane reduce the force necessary to lift up an object?
Yes. It is easier to push an object up a plane than lift it straight up. It does not reduce the total amount of energy needed to lift it up.
Does the advantage of using an incline plane to lift an object is that it reduces the amount of applied force?
Yes, it makes it easier to push the object up.

When your in a pool you can easily lift a person up but when you are in land you can't lift that person?
The weightlessness in the pool makes it easier to lift someone while gravity often makes it hard.
What are the functions of a first class lever?
It makes it easier for the effort force [such as your hand] to lift the resistance force [such as a heavy object].
