Quick comprehension check
“A person uses a ramp to push a 50 N box up to a height of 1 meter. If the person only needs to apply a force of 25 N to push the box up the ramp, how far must the person push the box along the ramp's surface? A lever allows a person to lift a heavy rock with only 100 N of force. If without the lever, the rock would require 400 N of force to lift, how does the distance over which the 100 N force is applied compare to the distance the rock is lifted?”
