Again "lifting" is increasing the potential energy of an object by increasing its altitude. The means of lifting is irrelevant to this definition. Sliding a stone upward on a ramp IS "lifting".
"irrelevant to what definition" ? What definition are you referring to? Increasing it's altitude is only useful, if you permit Gravity to take effect. Using 1 stone to lift another similar stone, is useless as a method of building.
Yes, a ramp (Incline Plain) is lifting. Though it requires less energy than a dead lift. The difference is, a man may not, be unable to perform the dead lift, where as, with the Incline Plain, he can accomplish the task.
NO ramp, No can do.
With ramp, Can do...
Are you familiar with what "Simple Machines" are and what they accomplish? There is 6 simple machines, and a Incline Plain is one of them.
Lever, Wheel and axle, Pulley. Inclined plane, Wedge, & Screw.
This is common knowledge.
