Question

Non uniform circular motion it s defined as the motion of an objects moving in a circular path with a varying speed ,since the speed is changing, there is tangential acceleration?

Answer 1

In nonuniform circular motion, an object moving in a circular path with varying speed has tangential acceleration, along with constant centripetal acceleration directed towards the center.

Step-by-step explanation:

Nonuniform circular motion occurs when an object moves along a circular path with varying speed, leading to the presence of tangential acceleration in addition to the constant centripetal acceleration. The tangential acceleration is the rate of change of the object's speed along the circle and is directed along the tangent to the circular path.

Contrary to nonuniform motion, uniform circular motion involves movement at a constant speed, meaning the magnitude of velocity doesn't change, but the direction does, resulting in a centripetal acceleration pointing toward the center of the circular path. The total acceleration of an object in nonuniform circular motion is the vector sum of tangential and centripetal accelerations.
