How much work(energy) is needed to lift an object that weighs 200N to a height of 4m?

My question: is weight the same as force? if not, how do I find the amount of force

  • Physics -

    work= force*distance=200N*4m=800Joules

    weight is gravitational force acting on some mass, in a gravitational field.

  • Physics -

    energy = mgh = 200*4 = 800J
