Physics And Measurement Question 101
Question: Dimensions of kinetic energy are
[ AFMC 1991]
Options:
A) $ ML^{2}{{T}^{-2}} $
B) $ M^{2}L{{T}^{-1}} $
C) $ ML^{2}{{T}^{-1}} $
D) $ ML^{3}{{T}^{-1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Kinetic energy = $ \frac{1}{2}mv^{2}=M{{[L{{T}^{-1}}]}^{2}}=[ML^{2}{{T}^{-2}}] $
