Question

as the pendulum swings freely, what is happening to its energy?(1 point) Responses KE converts to PE, and then total energy becomes zero KE converts to PE, and then total energy becomes zero KE converts to PE as it falls, and then PE converts to KE as it rises KE converts to PE as it falls, and then PE converts to KE as it rises PE converts to KE, and then total energy becomes zero PE converts to KE, and then total energy becomes zero PE converts to KE as it falls, and then KE converts to PE as it rises

Answer 1

are u sure

Answer 2

When are kinetic energy and potential energy equal in magnitude (equal in amount)?(1 point) Responses They are equal at every position. They are equal at every position. They are equal half-way between the top position and the bottom position. They are equal half-way between the top position and the bottom position. They are equal at the bottom position. They are equal at the bottom position. They are equal at the top position.

Answer 3

KE converts to PE as it falls, and then PE converts to KE as it rises.

Answer 4

I apologize for the confusion in my previous response. As the pendulum swings freely, the energy is constantly changing between kinetic energy (KE) and potential energy (PE). As the pendulum moves towards its highest point, the kinetic energy decreases and potential energy increases. As it swings back down, potential energy decreases and kinetic energy increases. Therefore, the correct answer is: KE converts to PE as it falls, and then PE converts to KE as it rises.

Answer 5

Kinetic energy and potential energy are equal at the bottom position of the swing.
