Question

Which of the following is not a scalar quantity?

• A. Temperature
• B. Coefficient of friction
• C. Charge
• D. Impulse
  

Answer 1

Answer: (D)

Impulse

Impulse $\left(I\right)$

$Force\propto \frac{1}{Timeinterval}$

$Force=I\frac{I}{Timeinterval\left(t\right)}$

$I=Force\times Timeinterval$

$I-F.I$

Since force is a vector quantity and impulse is the product of the sudden force applied and the time interval to bring equivalent the system. So Impulse also a vector quantity which have same direction to the force applied.
