It's all about momentum. When the bus is standing still, your body is standing still and has no momentum. When the bus begins to move, you body wants to stay stationary. Because it's resisting the acceleration of the bus, you don't accelerate with the bus and therefore get pushed backwards.
why dose one tend to fall backward on a bus when it starts out from a stand still why dose one tend to fall backward on a bus when it starts out from a stand still
The forward momentum forces you back.
When a bus starts moving forward, the inertia of the body tends to resist this change in motion. As a result, the body leans backward in reaction to the bus acceleration before adjusting to the new motion.
When a bus accelerates, the force of the bus moving forward through the inertia pushes passengers backward. Additionally, passengers may lean backwards instinctively to counterbalance the force and maintain their equilibrium.
Passengers on a bus tend to fall backward when it starts suddenly due to inertia. As the bus accelerates forward, the passengers, who were initially at rest, want to stay at rest due to their inertia. This causes them to lean back or fall backward as the bus moves forward.
Passengers fall backward when a bus starts suddenly because of inertia. Inertia is the tendency of objects to resist changes in their state of motion. When the bus accelerates forward, the passengers' bodies want to stay at rest due to inertia, causing them to fall backward.
Cherish
No long hair need not fall , just because it is long.
No, ladybugs can't fly backwards. Ladybugs are often hard pressed to even fly straight. If you watch them, they tend to land without much reason, as they hit things hard, and unbalanced.
Birth rates rise as death rates fall?
No, a donkey's tail does not fall off. This is in reference to the animal. However, donkey tail plants do tend to fall off.
When a bus accelerates, the force of the acceleration pushes you in the opposite direction (Newton's third law). Your body, still at rest, doesn't immediately move with the bus, causing you to fall backwards until your body catches up with the moving bus. This is similar to how you lean back when a car accelerates.
