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,
Linear Impulse 1
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

= 21

Where,

2= m 2

1 = m 1

Linear Impulse 2

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
