The diagram shows the path of a pendulum bob that has been released. Which describes the kinetic energy of the pendulum bob? A. It increases as it travels from its maximum amplitude to its resting point. B. It decreases as it travels from its maximum amplitude to its resting point. C. It decreases at the arm, but increases at the pivot point. D. It remains the same throughout the period.
WHAT DO YOU THINK?
i dont know please help i will give a medal!!!
HINT: KE always depends on the speed the particle has..
is it b?
the maxim amplitude is where the object tends to come to an stop for a while. at that point the speed gets down to zero and then starts increasing. It will be maximum where it reaches its resting point. so it is a...
