Why is there only a radial component of acceleration present if a body is undergoing uniform circular motion whereas in non uniform circular motion both tangential and radial component of acceleration are present?
dreamLord said:It can be any force which has a component along the tangential direction. Any force which is perpendicular to the (instantaneous) velocity will not change it's magnitude. All other forces will have a component along the tangential direction.
andyrk said:in non uniform circular motion velocity changes and there are one radial and one tangential component of acceleration. Why does the latter one have to be tangential?
andyrk said:Then why does it have to be a tangential force? Because in non uniform circular motion velocity changes and there are one radial and one tangential component of acceleration. Why does the latter one have to be tangential?
Radial acceleration in uniform circular motion is the acceleration that an object experiences when moving in a circular path at a constant speed. It is always directed towards the center of the circle, and its magnitude depends on the speed of the object and the radius of the circle.
The formula for calculating radial acceleration is a = v^2/r, where a is the radial acceleration, v is the speed of the object, and r is the radius of the circle. Alternatively, it can also be calculated using the formula a = ω^2r, where ω is the angular velocity of the object in radians per second.
Yes, radial acceleration and centripetal acceleration are the same. Centripetal acceleration is the acceleration that is directed towards the center of the circle, while radial acceleration is the component of that acceleration along the radius of the circle.
The direction of radial acceleration is always towards the center of the circle. This means that it is perpendicular to the velocity of the object and points inward towards the center of the circle.
Yes, radial acceleration can be negative. This indicates that the object is slowing down and moving towards the center of the circle. It is important to note that the magnitude of the acceleration is always positive, as it is dependent on the speed of the object and the radius of the circle.
