explain !!!

just chill

Meaning:

Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions).

Function:

Kinematics aims to provide a description of the spatial position of bodies or systems of material particles, the rate at which the particles are moving (velocity), and the rate at which their velocity is changing (acceleration).

Variable:

Kinematic variables allow the description of the motion of a body without reference to variables that act to change the motion of the body. 

Position:

Kinematics involves position, velocity and acceleration (and their rotational equivalents).

Position is the point in space that an object occupies, this needs to be defined in some coordinate system. Velocity is the rate of change of position with respect to time. Acceleration is the rate of change of velocity with respect to time.

Hope the concept of kinematics is clear to you :)

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.

there are no correct statementd on the list of choices you provided.
