Question

A child is swinging back and forth 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 one to two sentences, describe these points and which type of energy is at a maximum at each point.
PLZ HELP I JUST NEED A SIMPE ANSWER

5O POINTS AND I WILL MARK Brainiest

Answer 1

Answer:

The maximum potential energy of the child will be maximum at the two end points.  

The maximum kinetic energy of the child occurs at the lowest point of the swing.  

The potential energy of the child depends on the displacement of the child.  

P.E = mgh  

The maximum height attained occurs at the two end points of her swing motion.  

Thus, the maximum potential energy of the child will be maximum at the two end points.

The kinetic energy of the child depends on the velocity of the child  

K.E = ¹/₂mv²  

The maximum velocity of the swing occurs at the lowest point of the swing.  

Thus, the maximum kinetic energy of the child occurs at the lowest point of the swing.

Hope this helps!

Answer 2

At the his best point because the higher you go, the more potential energy you have and when going down the swing you gain kinetic energy. The faster you go down, the more kinetic energy. Hope this helps!!!
