Why walking up an inclined plane is easier than climbing stairs?
An inclined plane is a simple machine. An inclined plane is a ramp used to reduce the effort needed to raise or lower an object over a vertical height. It is easier to climb stairs to get to a second floor than to climb straight up a rope. It is easier to walk up a long, gentle hill than to climb up a short, steep hill both condition work is done by gravity which is conservative force. So work is same. But if we will take friction force then for your kind information total world done on plane will be more than stairs due to longer path of plane where against of non conservative force. The following are examples of inclined planes: * Loading ramp * Stairs or wheelchair ramp * Mountain road * Threaded screw. The ancient Egyptians used inclined planes, or ramps, to move huge blocks of stone to build the pyramids.
