Explanation:
Statement A:
- When a bus suddenly starts moving forward, the passengers inside the bus will experience a force that causes them to fall forward. This is due to inertia, as the passengers tend to remain at rest until acted upon by an external force (Newton's First Law of Motion).
- The force of the bus accelerating forward causes the passengers to also move forward, leading to the sensation of falling forward.
Statement B:
- When a gun is fired, the bullet is ejected forward with a high speed. According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction.
- As a result, the gun experiences a recoil force that pushes it backward, but with a smaller speed compared to the bullet moving forward. This is why we observe the gun recoiling backward when fired.
Therefore, in this scenario, Statement B is true as it explains the concept of recoil force and the movement of the gun when a bullet is fired.
