6. Explain why a lever is more efficient than a ramp.
[[#|Answer]]:
A lever is a more efficient machine than a ramp because there is less friction. This is due to the fact that when you push something up a ramp the two surfaces are constantly rubbing together causing friction. Although there is still friction when using a lever, there is not as much because there is less surface area rubbing.
