Now check your hypothesis by investigating two Tracker videos: Ball Drop and Large Ball Drop. Open the Tracker experiment: Ball Drop . Watch the movie by clicking on the play button. (The other video controls allow you to “rewind” the video or step forward or backward one frame at a time.). Watch the video to go ahead with the activity. Now, keep the Ball Drop video open, and also open the Tracker experiment Large Ball Drop and watch that video. For the Ball Drop experiment, observe the graph of the vertical displacement of the small ball against time (y vs. t). What can you say about the vertical displacement of the small ball? What graph shape is this? What does this shape tell you about the mathematical relationship between y and t? For edmentum

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

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.
