Circular Motion Acceleration Concepts

Which of the following is the correct formula for calculating centripetal acceleration?

What unit is used to measure angular acceleration?

How is tangential acceleration calculated?

Which type of acceleration is always directed towards the center of the circle?

When does centripetal acceleration become significant?

What is the relationship between linear acceleration and angular acceleration?

There are three types of acceleration when dealing with objects in circular motion: angular acceleration, tangential acceleration, and centripetal acceleration.
Angular acceleration is based on linear acceleration and is represented by the symbol alpha, calculated as the change in angular velocity over time.
Angular acceleration is measured in radians per second, reflecting the angle of change in circular motion.
Tangential acceleration is directed tangent to the circle and is calculated by multiplying angular acceleration by the radius of the circle.
In tangential acceleration, meters per second are used instead of radians to convert angular motion to linear motion.
Centripetal acceleration always points towards the center of the circle and is based on uniform circular motion.
Centripetal acceleration is calculated by the formula a = v^2 / r, where v is the tangential velocity and r is the radius of the circle.
Centripetal acceleration is significant in cases where the speed remains constant but the direction of motion changes continuously in circular motion.
