Question

Dimensional formula of rotational kinetic energy

Answer 1

Answer:

dimensional kinetic energy

Explanation:

1×mv^2/2

1/2 ×[M][LT^-1]^2

[M][L^2T^-2]

[ML^2T^-2]

Answer 2

$\huge\sf{\underline{\underline{\pink{Answer:-}}}}$

Total kinetic Energy of rotating object is the sum of kinetic energy of all individual particles of an object. so Rotational kinetic energy (KR) = ∑ 1/2 (mv2) = 1/2 ∑ (m r2 ω2) = 1/2 (∑ m r2) ω2. We can also write it as KR = 1/2 Iω2. ——- (Moment of Inertia (I)= ∑ m r2 ).
