Which of the following expressions gives a quantity that can be measured in joules (J)? [Assume that all quantities are magnitudes.]
The answer is B. Can someone explain how to solve this one?
Hi,
The answer will be B because work is a form of energy and
work= Force x displacement
Force= mass x (velocity/time)
work= mass x (velocity/time) x displacement [v=d/t]
work = mass x velocity x velocity [p=mv]
work= momentum x velocity
