|The property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force. So the object or passenger moves forward direction.|

|Sir Issac Newton's first law of motion speaks volumes about this phenomena. It speaks about Inertia which actually means " a tendency to do nothing". In simple words if you are idle, you remain so till you are woken up. or conversely,if you are active and you remain so till you are stopped from doing so.
SO, WHAT HAPPENS, IN THE ABOVE TWO STATES OF YOUR PREOCCUPATION?
You actually get a shock of your life when shaken up from either of your above situations.
The first case as above said is called " THE INERTIA OF REST" and the second case is called " THE INERTIA OF MOTION"
Now let us get this idea clear " THE INERTIA OF REST" alright?
We are sitting in a bus which is stationary, we have taken our seats, and feel well anchored. Our feet is firmly on the floor of the bus and our back is firmly settled on the back rest, however our head is free at this moment, so as to say it does not have a firm ground ( head is free moving in short).
Then what happens is? The bus starts moving forward with a jerk and since the feet and back has support unlike yr head, it does not move as it is in a state of rest, however the bus moves forward yr head tends to remain in its place, rather bus has moved forward and head is somewhere back wards, that means yr head goes back with a jerk as if trying to retain its original position. Body moves forward with the bus as feet and back as parts of the bus but head refuses to do so. THEREFORE THE JOLT. Now try to imagine there was no back rest, you would have got floored.
If you get the hang of the above situation, do I have to speak much about the second situation at all? " THE INERTIA OF MOTION" ? HUH.
You decide, as every other situation remains the same except now the bus is in motion and so is yr feet and back, yet the head is free moving.
Tell me the result.( Clue" head is free moving with the motion of the bus and tries to move with it but bus stops with a jerk, in short every other body part which is in contact with the bus stops but the head moves forward)

|When we are in a moving bus, we too are in motion. When the bus stops suddenly, our feet which are in contact with bus come to rest immediately, but our upper part of body is still in motion. So due to inertia of motion, we lean forward.|

|Because our body in motion when bus is running. Bus is suddenly stop then our body is suddenly comes in rest that's why our body is going forward.|

|When the bus starts suddenly the lower part of the body which is contact of the bus come to state of motion but he upper part due to inertia of motion wants to be at motion that's why the passenger lean backward.|
|Milton Henschel Aboagye said: (Jul 9, 2016)|
|Our body is said to be in motion whenever a bus we are in starts to move. Our body will be forced to stop moving when the bus comes to rest unexpectedly or suddenly. Due to this unexpected occurrence, our body will be forced to go forward due to inertia which is associated with motion.|

|Very helpful information, thank you.|
