Work is force times distance,and since the force is increased on the larger piston,the distance the force is applied over must be decreased.The work of the small piston,100 newtons multiplied by 0.5 meter (50 cm) is 50 joules (J),which is the same as the work of the large piston,500 newtons multiplied by 0.1 meter (10 cm).

做功等于力乘以距离,由于大活塞施加的力增大了,施力的距离就必须缩短.小活塞做的功为100牛顿乘以0.5米（50厘米）,等于50焦尔（J）,这与大活塞做的功——500牛顿乘以0.1米（10厘米）——是相等的.
