MCQ
Dimensions of kinetic energy are
- ✓$M{L^2}{T^{ - 2}}$
- B${M^2}L{T^{ - 1}}$
- C$M{L^2}{T^{ - 1}}$
- D$M{L^3}{T^{ - 1}}$
✓
Answer
Correct option: A.
$M{L^2}{T^{ - 2}}$
a
(a) Kinetic energy = $\frac{1}{2}m{v^2} = M{[L{T^{ - 1}}]^2} = [M{L^2}{T^{ - 2}}]$
(a) Kinetic energy = $\frac{1}{2}m{v^2} = M{[L{T^{ - 1}}]^2} = [M{L^2}{T^{ - 2}}]$
