Question

When is kinetic energy equal to potential energy in bob?

Answer 1

Answer:

Explanation:

If you divide the path of the pendulum into four equal lengthed parts, your answer is at A and B.

Answer 2

$\blue{ \huge{answer \: }}$

In a pendulum a Bob is hang and it is moved by taking at a certain height ✓ .And it then it goes from one maximum point to another with a certain velocity but it's not constant .At the regular intervals if time the velocity of the Bob decreases due to the frictional force produces at the joining of the string of bob and the holder surface ✓

And during the movement the Bob gets maximum potential energy at the maximum height and then when it comes doin the potential energy get converted into kinetic energy at the regular intervals and at the normal the kinetic energy of the Bob becomes maximum ( all the potential energy get converted into the kinetic energy) And Then it again starts it's journey to get at the maximum height at the another sides same way then there something happens reverse the kinetic energy is converted into potential energy in regular amount at regular intervals of time ✓ So again it attains the maximum potential energy at the same maximum point .So this happens continuously.

A/Q, The point where the kinetic energy is equal to the potential energy is the mid point of PQ and PR see the attachment ✓ But here the energy will be half the original amount .
