Question

Give important points of Tangential acceleration ??

Answer 1

Heya...!

1. If tangential acceleration is directed in the direction of velocity then the speed of particle increases

2. if tangential acceleration is directed opposite then speed of particle decreases

3. Tangential acceleration is responsible for changing speed of particle

4. in vector form .... a= r× alpha

$a = r \times \alpha$




Hope it helps u

Answer 2

HEYA!!!

=============××===========
Tangential acceleration (at) can be explained as the linear acceleration of a particle at any point on the curved path.


The acceleration can consist of two components one is the radial acceleration vector represented by ar and other is tangential component of acceleration at. Acceleration at any point in the curved point is equal to vector sum of tangential and radial acceleration. Path of the particle is shown above in the Figure 1. Direction of the acceleration vector is also shown which is at any point on the curved path is the resultant vector of vector ar and at. Magnitude of 'a' is given below,

a = (a2r+a2t)12
