Science 8 Q1 / Energy of Motion

a child is swinging back and fourth on a swing. changes in her kinetic and potential energy are happening each moment at which point or multiple points in her swinging would each of these two types of energy be at a maximum in 2 sentences describe these points and which type of energy is at it's maximum at each point

The maximum potential energy of the child on the swing occurs when the child is at the highest point of the swing's arc. At this point, the child has the most potential to convert the potential energy into kinetic energy as she swings downwards. The maximum kinetic energy occurs when the child is at the lowest point of the swing's arc. At this point, the child is moving at her fastest speed, thus having the highest amount of kinetic energy.

During the child's swing, her kinetic energy will be at its maximum at the lowest point of the swing. This is because she has the highest speed at this point, resulting in maximum kinetic energy. On the other hand, her potential energy will be at its maximum at the highest point of the swing when the child is momentarily at rest before changing direction. This occurs when her height from the ground is highest, leading to maximum potential energy.

To determine the points where the child's kinetic and potential energy are at a maximum during swinging on a swing, you need to understand the concept of mechanical energy. At the highest points of her swing, such as when she reaches the peak on each side, her potential energy is at a maximum because she is elevated from the ground. On the other hand, at the lowest points of her swing, such as when she reaches the bottom center point, her kinetic energy is at a maximum because she has the maximum speed there due to the force of gravity.
