Answer:
Explanation:
Analogy:
Who does more work:
Work done is defined as the product of force and distance. Work is done when force moves a body in a particular direction.
In this case, work done is the same thing as the potential energy of the weight.
Work done = potential energy = m x g x h
Mass of weight = 100kg for both Mike and Brian
g is the acceleration due to gravity
h is the height
Since they lifted the weight through the same height;
Work done by Mike = 100gh
Work done by Brian = 100gh
Both Mike and Brian does equal work
Who generates more power:
Power is the rate at which work is done;
Power =
Power generated by Mike = = 50gh
Power generated by Brian = = 33.33gh
We can see that Mike generated more power
