The forward momentum forces you back.
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.
It is because of Newtons first law of inertia. When the bus moves forward your body is inclined to stay in the same position, so it is as if the floor is moving out from under your feet.
The sound takes time to travel from up in the air down to the ground. So, if the plane is directly overhead, the sound takes a little time to reach you, so that by the time you hear it, the plane has moved a bit. The sound is loudest when the plane is directly overhead, which is how we tend to judge where the sound is "coming from," so it appears to be coming from behind the plane. This is called the Doppler Affect.
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
No long hair need not fall , just because it is long.
The Russians tend to be unwilling to give out figures like that.
Birth rates rise as death rates fall?
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.
They have leaves that tend to lie in a plane at right angles to the strongest light, hence usually north and south.
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.
Because natural satellites tend to lie in the primary's equatorial plane.
