|Class 11 Physics Laws of Motion||Inertia|
Inertia is the resistance of a body to change its state of motion.
Have you experienced jerk when brakes are suddenly applied to the vehicle?
This happens because initially the car was in motion; the body was also in motion. Later, due to the application of brakes, the car came to rest; but the body due to its inertia still wants to be in motion. Therefore, the body doesn’t come to rest at once and experiences jerk.
