Question

What is the value of tangential acceleration in U.C.M.?

Answer 1

Answer:

Explanation:

=> Tangential acceleration is a measurement of quick changes in a tangential velocity in rotational motion.

=> Tangential acceleration is the product of Radius of the rotation and angular acceleration.

∴ a_tan = rα

where,

a_tan = tangential acceleration

r = radius of the object's rotation

α = angular acceleration ( radians.s^-2)

=> The value of tangential acceleration in uniform circular motion :

In uniform circular motion (U.C.M), It's angular valocity is constant.

a = dw/dt

but, w = constant

∴ a = 0  

Thus, the value of tangential acceleration in uniform circular motion is zero.

Answer 2

Explanation:

when velocity change as magnetude then the acceleration is called tangential acceleration .,
