Thank you for the extra information, really appreciate it :)PeroK said:"When flight attendence pour some water/juice etc the liquid comes straight down and not on a different angle."
That's a good observation. The aircraft is moving almost inertially (i.e. with negligible acceleration), so things inside the aircraft behave according to Newton's laws. And, objects dropped fall straight down.
Newton's First Law of Motion, also known as the Law of Inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
In this scenario, the boy and the train are both in motion, so they will continue to move at a constant velocity unless acted upon by an external force. When the boy jumps, he is briefly in a state of zero velocity in relation to the train, but since the train is still moving, he will eventually land back on the train due to the train's inertia.
Inertia is the resistance of an object to change its state of motion. In this scenario, the train's inertia keeps it moving at a constant velocity, while the boy's inertia keeps him moving in a straight line until an external force (such as gravity) acts upon him.
Newton's First Law of Motion can be observed in many everyday situations, such as when a car stops suddenly and passengers continue to move forward due to their inertia, or when a ball rolls to a stop on a flat surface due to friction and air resistance.
This law is the basis for many technologies, such as seatbelts and airbags in cars, which are designed to protect passengers from the effects of inertia in the event of a sudden stop. It is also used in sports, such as in long jump and pole vault events, where athletes use their inertia to propel themselves forward.
