Why is it that when you're inside a bus and the bus is in motion, whenever you toss a coin or a stone, that object will still be in the same place where it used to be?Why is it that it will not be moved backwards?

The bus is moving at a certain speed and so is all the object in it. When you throw the coin up it keeps its forward momentum and add upward and downward momentum.

If you observe the motion of a basket ball and the players, you can see the player catching the basket ball after throwing it in air.
As the ball comes down the player runs and catches it.
In the running bus, you have the advantage that you need not run, but the bus takes you to the exact place where the coin falls.
For an out side observers, even though you throw it vertically, the coin follows a parabolic path.
Suppose you throw the coin (vertically) when the bus crosses a tree on the road.
For an observer out side, the bus, you and the coin are moving in a particular direction.
When you throw the coin, the bus and you are leaving the tree. The coin while leaving the tree it also goes up.
(like the basket ball).
While the bus and you reach another lamp post,
the coin travels from the point near the tree, goes up and again lands a point near the lamp post in a parabolic path.
For you in the bus, it appears as if it has gone vertically up and down.

Hi
Everything is moving on the bus. Leave the coin in the air in the bus long enough and it WILL slow down..eventually.
Stop the bus by bashing into a wall and everthing in it will try to keep going, you and the coin.
Read about inertia and relative motion, absolutely fascinating.
Question for you. Tie a bird to the back seat in your car and get it to fly ahead. Will it make the car go faster? NO because it is pushing back on the air in the car which is pressing on the back windscreen

The coin is moving at the same speed as the bus

Hi,if bus is moving with non acceleration the coin will fall in the same place,if the bus is in acceleration then the coin will fall infront of u,if it is in decelearation the coin will fall behind u.

Well first of all if you are in the bus that is moving the object will move also, BUT speaking as a retired bus driver, why are you throwing things? it is a safety hazard.

I think it was Galileo that first observed that an object will stay in motion until it is affected by another force. I don't think he made a law out of it though, like Newton did.

beacuse that coin is in the bus like you and it is moving in the speed of you and the bus

when matter flows it flows together so when a person gets on a bus you become the bus.

It's relative velocity to you is zero because you're both moving with the train.
