i still do not understand?? can someone please help me out???

(a) why is the centripetal force neede to keep a body moving in a circular path?

(b) In what direction does a centripetal force accelerate the body on whic it acts??

(c) Upon what threee factors does the centripetal force keeping a body moving in a circular path depend?

i realllyyyy need this for a presentation for physics. can someone please help me out?

(a) When moving in a circular path, a body must constantly change its direction towards the center of the circle. This requires a constant force that is perpendicular to the direction of motion.

(b) The direction that is always perpendicular to the equation of motion is the center of the circle.

(c) mass (m), velocity (V) and distance to the center of the circle (R)
