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.
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
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.
Newton's third law of motion explains this phenomenon: for every action, there is an equal and opposite reaction. When you bump into something, you exert a force on it, and it exerts an equal force back on you, causing you to fall backwards.
The person has inertia, the resistence to change in motion, so if the car starts accelerating forward, the person's body wants to stay at the same velocity as before, thus it slides backwards relative to the car. If there were no friction or a back of the seat to stop the person, the person would literally not move while the car moves out from under him, thus seeming to move backwards in the car while in reality the car is moving forward under the person.
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.

its like the bus is pulling your feet out from underneath you
stand
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.
The coach can stand there because if she starts to fall the coach can grab her and not let her fall to the groud
Backwards
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.
if they went in foward they would fall in the boat.
Divers fall backwards from a boat because it is often the easiest way to make a deep water entry from a small boat or rib.
If you have a group you can use them! Stand behind a volenteer and have them fall backwards. Explane that gravity pulled that person down. Dont forget to catch them. -amy h
Imagine that you are standing inside a stationary bus. Suddenly the bus starts moving and you fall backwards. This is due to the inertia of your body. When the bus was at rest, you were also at rest. When the bus started moving, your legs went with the floor of the bus due to friction. But the upper part of your body tends to continue in its state of rest (inertia of rest). As a result you fall backwards.
The Roman soldiers fell backwards because they were surprised and overwhelmed by the unexpected attack from the enemy.
