Question

Q.6. What are the dimensions of angular acceleration "a" in the formula:
a = r a where
linear acceleration
r=radius.
a​

Answer 1

Answer:

at=rΔωΔt a t = r Δ ω Δ t . These equations mean that linear acceleration and angular acceleration are directly proportional. The greater the angular acceleration is, the larger the linear (tangential) acceleration is, and vice versa

Answer 2

Answer:

A =

$a = {l}^{1} {t}^{ - 2}$

angluar acceleration=a*r

dimensions of radius =L

so a*l=

${l}^{1} {t}^{ - 2} \times l \\ = {l}^{2} {t}^{ - 2}$
