Discuss the kinetic and potential energy of the ball on the end of a pendulum as it swings from point to energy as the ball moves from point A to point B. In your discussion, answer the following questions:
A to point B. Explain the kinetic energy and potential energy of the ball at each point and what happens
When is the kinetic energy of the ball zero and when is it at its highest? When is its potential energy at its
lowest and at its highest? What happens to the kinetic energy and potential energy between point A and
point B?

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
