Acceleration is a change in velocity either in its magnitudei.e. speedor in its direction or both. In uniform circular motion the direction of the velocity changes constantly so there is always an associated acceleration even though the speed might be constant.Centripetal acceleration is the idea that any object moving in a circle will have an acceleration vector pointed towards the center of that circle. Centripetal means towards the center.This inward force is sometimes referred to as a centripetal force where centripetal describes its direction. Without this centripetal force an object could never alter its direction. The fact that the centripetal force is directed perpendicular to the tangential velocity means that the force can alter the direction of the objects velocity vector without altering its magnitude.

That depends on the situation on the problem you are trying to solve. If speed is constant maximal centripetal acceleration occurs where the radius of curvature is smallest - for example in the case of a parabola at its vertex.Use the centripetal acceleration equation and solve for speed. Substitute values for the acceleration due to gravity on earth and the radius of the Earths orbit (also known as an astronomical unit). Substitute values for the acceleration due to gravity on earth and the radius of the Earths orbit (also known as an astronomical unit).18.02.2014 In this video we look at how to find the magnitude and direction of the acceleration of objects. We call the resulting direction and magnitude of the acceleration we find an acceleration vector.Autor talkboard.com.auAufrufe 12KVideolnge 13 Min.

The magnitude of this centripetal acceleration is found in Example 1. (b) A particle of mass in a centrifuge is rotating at constant angular velocity . It must be accelerated perpendicular to its velocity or it would continue in a straight line. The magnitude of the necessary acceleration is found in Example 2.
