Question

Which one of the following is a vector quantity?

• A. Energy
• B. Pressure
• C. Momentum
• D. Work

Answer 1

Answer: (C)

The correct option is C Momentum

• Energy, Presssure and Work are scalar quantities because only magnitude is required to describe them.
• From $\overrightarrow{P}=m\overrightarrow{v}$, direction of momentum will be same as direction of velocity.
  
• Therefore momentum has both magnitude and direction. Hence momentum is a vector quantity.

Option C is correct.
