Q: Which of the following statements is false
  • A. When a bus stops suddenly, a passenger sitting in the bus is jerked backwards.
  • B. When a person jumps from a moving bus, he falls.
  • C. When a rotating fan stops, it rotates for some time.
  • D. When a bus stops suddenly, a passenger sitting in the bus gets a shock in the front
Correct Answer: Option A - 1. When a moving bus stops, the lower part of our body in contact with the bus comes to rest while the upper part of our body tends to keep moving due to inertia of motion. Hence, we fall (or forwards) 2. When the bus accelerates from rest, the lower part of our body comes into motion along with the bus while the upper part of body tends to remain at rest due to inertia of rest. Hence we fall backwards.
