In science work is defined as the force needed to move an object a certain distance The amount of work done per unit of time is called power Suppose you and a friend are helping a neighbor to reshingle the roof of his home You each carry 10 0 bundles of shingles weighing 300 newtons apiece up to the roof which is 7 00 meters from the ground The amount of energy required to accelerate the same car from 10 mph to 20 mph is a the same b twice as much c three times as much d four times as much Answer c To go from 0 to 20 mph requires 4 times as much energy as from 0 to 10 mph So it require 3 times as much energy to go from 10 to 20 mph than from 0 to 10 mph 5
