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 t_{1} and t_{2}. 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-

_{x}dt = m _{x2} – m _{x1}

_{y}dt = m _{y2} – m _{y1}

_{z}dt = m z_{2} – m z_{1}
