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 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.
there is a type of device on the train of the rollercoaster that is known as the "chain dog". the "chain dog" grabs the hill so it doesn't roll backwards, but it still allows the train to go upwards by the pulling motion of the chain (note: the bolded "chain" is not the chain dog, the chain dog holds while the regular chain pulls)
it stands for distance
If you fall down, that's gravity. If you stand up and stand on your feet (as opposed to floating through space), that's gravity.

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
Yes--because of Newton's first law, the passenger wishes to stay in its constant state of motion, which is standing still in this case. Hence, when the train starts to move forward, the passenger will want to stay at the point he/she was and will fall backwards.
Backwards
if they went in foward they would fall in the boat.
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
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.
YES for example if you stand on water you fall so it does and if your still saying does it work in the water well if i put your feet 5 centimeters in water you would still fall down.
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.
