A ramp like the one in the Figure below is another example of an inclined plane. Inclined planes make it easier to move objects to a higher elevation. The sloping surface of the inclined plane supports part of the weight of the object as it moves up the slope. As a result, it takes less force to move the object uphill. The trade-off is that the object must be moved over a greater distance than if it were moved straight up to the higher elevation. You can see several other examples of inclined planes at this URL
Mark was putting a ramp in for his parents. His mother had recently started using a cane and sometime a wheelchair. She had a lot of difficulty climbing the stairs. Mark hoped the wheelchair would make her life a little easier.
Is the distance to the door longer or shorter with the ramp?
