It would be much easier to lift a truck on the moon because there is no gravity out in space, so it would be simpler and not as heavy.
Wow. There is less gravity on the moon so inturn that makes it easier to lift weights.
No. An object on Mars would weigh about 38% of what it does on Earth. The _mass_ would be the same, however, so you would be able to lift it easier, but pushing it and stopping it would be the same as on Earth.
When you jump, you exert a force greater than the force of gravity to achieve a net positive upward acceleration - at least until your feet leave the ground and you quit exerting force. The net upward force is Fnet = (force you push off with) - (force of gravity) Because the moon has less mass than the earth, the force of gravity is less. As a result, the force you exert to jump on earth would give a higher net upward acceleration on the moon and allow you jump higher. Even with the extra weight of their space suits, the net upward force they can generate is more than they could when jumping without their suits on the earth.

As common sense would suggest, it is easier for them to lift light 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.
because we can't lift it with our hand
Straining to life heavy objects can cause a male to get a hernia. It can also cause back issues if he doesn't lift correctly.
They had wheel barrels and bucket systems so that they could lift water and heavy objects easily.
By using the principle of levers.
For Somethings
The lever.
You shouldn't drink alcohol, smoke or lift heavy objects
Yep! I am not sure what class but it is! Levers help lift heavy objects. Levers work by the farther you are from the fulcrum or pivot as compared to the heavy objects, the lesser the force you will need to lift or pull the object.
Both, and neither. Both, because levers successfully assist people in lifting heavy objects (which requires force) and opening things (which requires force). Neither, because the definition of a lever has nothing to do with how the theory is used.
