FLASHCARD QUESTION

Front

What is centripetal motion?

Back

Centripetal motion refers to the motion of an object moving in a circular path, where it is constantly changing direction due to the centripetal force acting towards the center of the circle.

FLASHCARD QUESTION

Front

True or False: An object in circular motion is constantly changing its velocity.

Back

True

FLASHCARD QUESTION

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration that occurs in circular motion, directed towards the center of the circle, and is calculated using the formula a_c = v^2 / r, where v is the velocity and r is the radius.
