Statement A: A passenger falls forward when a bus suddenly starts moving in the forward direction.
Explanation:
When a bus suddenly starts moving in the forward direction, the passengers inside the bus tend to fall forward. This can be explained by Newton's first law of motion, also known as the law of inertia. According to this law, an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force.
When the bus starts moving forward suddenly, the passengers inside the bus were initially at rest. As the bus starts moving, the passengers tend to remain at rest due to their inertia. However, the floor of the bus exerts a force on the passenger, accelerating them forward. As a result, the passenger falls forward.
Statement B: A gun recoils backward with a smaller speed than the bullet moving forward.
Explanation:
When a gun is fired, the bullet moves forward with a high speed. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When the bullet is propelled forward with high speed, the gun experiences a recoil force in the opposite direction. This recoil force causes the gun to move backward.
However, it is important to note that the gun recoils with a smaller speed than the bullet. This is because the momentum of the gun and the bullet is equal and opposite due to Newton's third law. The momentum of an object is given by the product of its mass and velocity. Since the mass of the gun is much larger than the mass of the bullet, the gun moves backward with a smaller velocity compared to the bullet's forward velocity.
Therefore, statement A is true because a passenger falls forward when a bus suddenly starts moving in the forward direction due to inertia. Statement B is also true because a gun recoils backward with a smaller speed than the bullet moving forward due to Newton's third law of motion.

When the bullet is propelled forward with high speed, the gun experiences a recoil force in the opposite direction. This recoil force causes the gun to move backward.

Therefore, statement A is true because a passenger falls forward when a bus suddenly starts moving in the forward direction due to inertia. Statement B is also true because a gun recoils backward with a smaller speed than the bullet moving forward due to Newton's third law of motion.
