What are examples or centripetal acceleration?

Centripetal acceleration is necessary, and is present, whenever any object

moves in a closed path, or along any part of a circular path. Some examples

I can think of are:

- - a planet or a comet in orbit around the sun

- - a moon in orbit around a planet

- - the little ball making circles around the spinning roulette wheel

- - a stone tied to the end of a string, when you spin it around your head

- - the end of the spinning string on a weed-whacker

- - the tip of the blade of a fan or a windmill

- - any little bit of rubber on a car tire or bicycle tire, when they're moving

- - a strawberry seed spinning around the inside of the blender jar when you're

making a smoothie

- - a car driving around a curve in the road

- - you on almost any amusement park ride; whenever you're not moving in a

straight line, you're experiencing centripetal acceleration.

centripedal acceleration:

⇒ the moon in orbit around a planet (or the sun).

⇒ The Earth (or an other planet) in orbit around the sun.
