What Is the Mechanical Advantage of an Inclined Plane?

The mechanical advantage of an inclined plane can be calculated by dividing the inclined plane’s length by its height. The mechanical advantage of an inclined plane represents how less work is needed to move an object up a ramp compared to directly lifting it from the ground.

Inclined planes are often used when heavy objects need to be moved to a higher vertical position. Instead of lifting the object up, it can be pushed up a ramp. The ramp allows a lower amount of force to be spread out to accomplish the same task. This is because work is equal to force multiplied by distance. The work stays the same, the distance increases, so the force required is less.
