Q. The passengers tends to lean forward When a running car stops suddenly because of__?
Answer: inertia of motion
Notes: When a running car stops suddenly, the passengers tend to lean forward due to inertia of motion. On applying brakes, the bus does stop but the passengers sitting in car remain in motion hence, as bus suddenly stop, they tend to continue in motion or going forward. Inertia is that property of a body due to which it resists a change in its state of rest or uniform motion.
