When a running car stops suddenly, the passengers tends to lean forward because of: (1) centrifugal force (2) inertia of rest (3) inertia of motion (4) gravitational force

Description : When a running car stops suddenly, the passengers tends to lean forward because of: (1) centrifugal force (2) inertia of rest (3) inertia of motion (4) gravitational force

Last Answer : (3) inertia of motion Explanation: When a running car stops suddenly, the passengers tend to lean forward due to inertia of motion. Inertia is that property of a body due to which it resists a change in its state of rest or of uniform motion.
