# What is tangential acceleration equal to?

**Tangential Acceleration**Formula. In rotational motion,

**tangential acceleration**is a measure of how quickly a

**tangential**velocity changes. It always acts perpendicular to the centripetal

**acceleration**of a rotating object. It is

**equal**to the angular

**acceleration**α, times the radius of the rotation.

Simply so, is tangential acceleration the same as angular acceleration?

**Angular acceleration** is the change in **angular** velocity divided by time, while **tangential acceleration** is the change in linear velocity divided by time.

Similarly, what causes tangential acceleration? **Tangential acceleration** arises when the object experiences a force parallel/antiparallel to the direction of velocity of the object which results in non uniform circular motion.

In this way, what is value of tangential acceleration in UCM?

The **value of tangential acceleration in U.C.M.** is zero. Because its angular velocity is constant. α=dωdt. ω=constant. α=0.

What is normal acceleration?

**Normal Acceleration**. the component of **acceleration** for a point in curvilinear motion that is directed along the principal **normal** to the trajectory toward the center of curvature; **normal acceleration** is also called centripetal **acceleration**. For rectilinear motion the **normal acceleration** is zero.
