Question

Is impulse a vector or scalar?

Answer 1

Explanation:

1. The average force throughout the time interval t is called the impulse. $Ft=I$
2. Time is a scalar while force is a vector. Since the scalar times vector is a vector quantity, the impulse is a vector quantity.
3. Impulse is defined as the rate of change of momentum in terms of momentum.
4. $P_2-P_1=I$, Where, $P_2$= Final momentum, $P_1$= Initial momentum, and $I$= Impulse
5. Momentum is a vector quantity because it is the product of mass and velocity.
   Impulse is a vector quantity since it is dependent on momentum.

Where, $F=$ Force, $I=$Impulse,$t=$ Time, and $P=$ Momentum

Hence, the impulse is a vector quantity.
