Question

a) Where does a pendulum have maximum i) potential energy ii) kinetic energy? ​

Answer 1

$\boxed{\huge\underline{\mathscr\purple{♡ANSWER♡}}}$

• At the highest point of its motion, kinetic energy is minimum (i.e. zero) and potential energy is maximum. The acceleration is a maximum at the end points of the swing, and a minimum (zero) in the middle, at the lowest point.

Answer 2

THE MAXIMUM POTENTIE L ENERGY AT EXTREME POSITIONS  AND MAXIMUM KUINETIC ENERGY AT MEAN POSITIONS
