Question

When is the kinetic energy of a pendulum the least?

Question 5 options:

On the path beginning the upwards swing.


Half the distance on the path traveling back down.


At the bottom of the swing.


At the top of the swing where it briefly stops before changing direction.

The Correct choice is ~

" At the top of the swing where it briefly stops before changing direction "

before changing the direction, it stops for a while therefore the kinetics energy is almost zero at that particular moment ~

Answer 2

The answer is D - At the top of the swing where it briefly stops before changing direction. This is where potential energy is at its highest, meaning that kinetic energy is at its lowest. When the pendulum is beginning its upwards swing, it has a lot of kinetic energy. When it is half the distance traveling down it also has lots kinetic energy. When it is at the bottom it as well has a lot of kinetic energy. The only time where the kinetic energy is least is when the pendulum stops to change direction. Any form of stopping forced the object to loose its kinetic energy.

I hope this helps! :)
