Question

Explain impulse or impulse of force. Write its unit and dimensional formula.​

Answer 1

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

Or, I = [M1 L1 T-2] × [T] = [M1 L1 T-1]. Therefore, the impulse is dimensionally represented as [M1 L1 T-1].

Answer 2

Answer:

The term Impulse is used to refer to fast-acting force or “impact”, Thus impulse can be defined as “The sudden force acting on an object for a short interval of time”. Conventionally represented by J. Sometimes by imp and expressed in N.

The dimensional formula of impulse is given by,

M1 L1 T-1

Where,

M = Mass

L = Length

T = Time
