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
2 answers
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.
