Question
As a bullet travels through the air, it slows down due to air resistance. How does the bullet’s momentum change as a result?
- Bullets momentum decreases
- Bullets momentum increases
- Bullet’s momentum stays the same
- Cannot say
Hint:
Bullet's momentum decreases.
The correct answer is: Bullets momentum decreases
Momentum is the product of mass and velocity. Since the velocity of the bullet decreases due to air resistance, the momentum also decreases. Hence we can say that as resistance or friction opposes the motion of the bullet, it's momentum decreases due to the decrease in it's velocity.
