Question

1. A bullet fired from a gun is more dangerous than an air molecule hitting a person, though both bullet and air molecule are moving with same velocity. Explain. 2. Why are road accidents at high speeds very much worse than accidents at low speeds?.

Answer 1

1. This is because of momentum.
Momentum = Mass x Velocity
The bullet will have a higher momentum than the air molecule because it has higher mass.

2. Likewise vehicles moving at high velocity will have higher momentum than vehicles that are moving slowly hence the accidents caused by high-velocity vehicles will be worse.

Answer 2

Answer:

Mass Of a bullet is much greater than the air molecule .

Explanation:

Therefore, even when both have almost the same speed, linear momentum of an air molecule. Hence the force required to

Stop a bullet will be much bigger than the force required to stop an air molecule. That's why a bullet fired from a gun is more dangerous than an air molecule..
