When a man jumping out of a moving bus falls forward?

The person is in a state of motion, but when they jump out and land on the ground, the lower half of their body comes to an abrupt stop. Due to the inertia of motion, the upper half of their body resists this sudden change in state and continues to move in the direction of the bus, causing the person to roll forward.

When a bus stops suddenly, its passengers tend to fall forward because due to their inertia the passengers tend to remain in a state of motion even though the bus has come to rest.

Effects of Inertia You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward. When the car starts moving again, your body tends to stay at rest. You move forward because the car seat exerts an unbalanced force on your body.

This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion. Hence, the passenger's are thrown forward.

And the bus stopped suddenly. I fell down. Because of Newton's Law of Inertia, which states: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

When a bus starts suddenly,its passengers tend to fall backwards because due to their inertia, the passengers tend to remain in a state of rest even when the bus starts moving.

MORE DETAILS

EXPLANATION: When a bus suddenly starts moving, the passengers fall backward due to the law of inertia of rest or 1st law of Newton.

The energy of the bus has to go somewhere, and the momentum too, as they are independently conserved. Part of the energy goes to heat, in the brakes and on the contact ground/wheels. Heat means photons, so photons may take away some momentum. But most momentum through friction is transferred to the ground .
