Question

If v = au in equation v and u are represente V& initial velocity & final velocity then what is the dimensional formal of 'a' is​

Answer 1

Answer:

Here u represents the initial velocity, v the final velocity, a the uniform acceleration, and t the time.

The dimensional formula of u is [M 0 LT −1 ].

The dimensional formula of v is [M 0 LT −1].

The dimensional formula of at is [M 0 LT −2 ][T]=[M 0 LT −1 ].

Here the dimensions of every term in the given physical relation are the same, hence the given physical relation is dimensionally correct.

Answer 2
