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.
How does a spring balance work?
to measure the weight of an object, hang the object on the hook of the balance, lift up the balance and take the reading. OR to measure the force needed to pull an object, attach an object to the hook of the balance, pull the balance and take the reading when the object moves.
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 it is easier to pull an object then to push it?
Actually, its not. It depends on the direction of the force vector use to push or pull. If the two directions are equal, and the position of the force vectors are consistent with each other, then the amount of force to push would be the same as the amount of force to pull. You are probably realizing by now that when you pull an object, there is a tendency to lift it up from the surface, reducing friction, while when you push an object, the tendency is to push it down on the surface, increasing friction. This is why you have to be very careful and consistent in how you measure things.

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.

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.
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 pull a submerged boat anchor to the surface than it is to lift onto the boat?
because the water pressure takes up some of the weight as you lift it in the water
