Centripetal acceleration is the acceleration that an object experiences when moving in a circular path. It is always directed towards the center of the circle.
The formula for calculating centripetal acceleration is a = v^2 / r, where a is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path.
The factors that affect centripetal acceleration include the velocity of the object, the radius of the circular path, and the mass of the object. A larger velocity or smaller radius will result in a larger centripetal acceleration, while a larger mass will result in a smaller centripetal acceleration.
Yes, centripetal acceleration can be negative. This can occur when the velocity and radius of the object are in opposite directions, resulting in a negative value for centripetal acceleration. However, the magnitude of the acceleration will still be the same.
Centripetal acceleration is the acceleration that an object experiences when moving in a circular path, while centrifugal force is a fictitious force that appears to push objects away from the center of rotation in a circular motion. Centrifugal force is equal in magnitude but opposite in direction to centripetal acceleration.
