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
KE converts to PE as it falls, and then PE converts to KE as it rises.
are u sure
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.
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.
Kinetic energy and potential energy are equal at the bottom position of the swing.
As the pendulum swings freely, the energy is continuously converted between kinetic energy (KE) and potential energy (PE).
Specifically, as the pendulum swings downward, its potential energy decreases and is converted into kinetic energy. As it reaches the lowest point of its swing, where it's momentarily at rest, all of its energy is in the form of kinetic energy.
Then, as it swings upward, the kinetic energy decreases and is converted back into potential energy. At the highest point of its swing, when it reaches its maximum height, all of its energy is in the form of potential energy.
Therefore, the correct answer is: KE converts to PE as it falls, and then PE converts to KE as it rises.
As the pendulum swings freely, its energy undergoes a continuous conversion between kinetic energy (KE) and potential energy (PE). The correct answer is: KE converts to PE as it falls, and then PE converts to KE as it rises.
To understand why this is the case, let's break it down step by step:
1. At the highest point of its swing, when the pendulum is momentarily at rest, it has maximum potential energy (PE) because it is at its maximum height above the equilibrium position.
2. As the pendulum begins to swing downwards, the potential energy starts to convert into kinetic energy (KE). The higher it falls, the more its potential energy decreases and its kinetic energy increases.
3. At the lowest point of its swing (the equilibrium position), the pendulum reaches its maximum speed and has maximum kinetic energy. At this point, its potential energy is at its minimum because it is closest to the lowest point of the swing.
4. As the pendulum starts to swing back upwards, its kinetic energy starts to convert back into potential energy. The higher it rises, the more its kinetic energy decreases and its potential energy increases.
5. The process continues as the pendulum swings back and forth, with the energy being continuously converted between kinetic and potential energy, while the total energy (the sum of KE and PE) remains constant. This process continues until it loses energy due to factors such as air resistance or friction.
So, in summary, as the pendulum swings freely, its kinetic energy converts to potential energy as it falls and potential energy converts to kinetic energy as it rises. The total energy of the pendulum remains constant throughout this cycle.
