Linear Impulse can be defined as the equivalent change in linear momentum in the same direction. The S.I. unit of Linear Impulse is Newton-second (N-s).

Let us consider force acting on the body be

Linear momentum can be given by,

dt

Suppose the force acts on the body between separate interval of time t₁ and t₂. Now, linear momentum can be given by,

It can be modified as,

= dt

= ₂ – ₁

Where,

₂= m ₂

₁ = m ₁

Components of Linear Impulse

Considering the components of linear impulse, it consists of x, y and z components. These are written as-

_xdt = m _x2 – m _x1

_ydt = m _y2 – m _y1

_zdt = m z₂ – m z₁
