Question

check the velocity of the v=u+at
​

Answer 1

Answer:

Let us check the dimensional correctness of the relation

v=

u+

at

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.
