i dont eve know!....im asking
When you include the effects of friction, it takes less force to move a light-weight object. If you can get the objects into a frictionless environment, then any force, no matter how small, can move any object, no matter how heavy.
Yes
the force, otherwise the rock would not move.
Because the force is acting to move the greater weight. A fully loaded large truck may weight 87,000 lbs more than the empty truck. More work must be performed to move that greater weight.

Same as light.

The heavy the crayon, it will roll down but it needs force to move it back up
The mass of the object (force of gravity) and the frictional force of moving the table are greater than the horizontal force that the boy is exerting on the table... so it won't move
about in between. if the car is too light it is probably no very strong (it will Break). but if it is too heavy it wont move very fast. hope this helps...
you have more energy.

I am not quite sure what you mean. To move heavy objects, you need a strong force - and that requires energy. Gold doesn't help with that - unless you pay somebody in gold to do it for you. A strong force can be achieved with a lever. If you want to construct your lever out of gold, you're certainly entitled to do that.
