Passengers are thrown forward when a moving vehicle suddenly stops due to inertia. Inertia is the tendency of an object in motion to stay in motion, so when the vehicle stops suddenly, the passengers continue moving forward until they are stopped by the seat belt or another object.
The passengers fall forward when the driver applies brakes suddenly because of inertia. Inertia is the tendency of an object to resist changes in its state of motion. When the bus abruptly decelerates, the passengers continue moving forward due to their inertia, causing them to fall forward.
When car was moving, passengers were also moving. When car suddenly stops, the moving passengers try to maintain their state of forward motion because of their inertia. so they move forward relative to their seats...
This happens because an object in motion tends to stay in motion
It is due to the physical law of INERTIA! All of the objects in the vehicle are travelling at the same speed as the vehicle itself. When the vehicle is suddenly stopped by an immovable object (e.g., a concrete wall) all unattached objects in the vehicle continue to move in the direction of travel until they also encounter the immovable object or the now-stopped vehicle. Even a common housefly in a vehicle going 75 mph is also going 75 mph, and if the car hits a tree at full speed, the fly hits the windshield at the same speed as the car hitting the tree.
The Law of Inertia states that an object in motion remains in motion and an object at rest remains at rest unless and unbalanced, outside force acts upon that object. Because the passengers are "attached" to the bus, they have the same inertia as the bus. But because the passengers are technically seperated, they have their own inertia. So when the bus is slowing down to a stop, the passengers inertia are to keep moving forward. As the bus moves back, the passengers want to keep moving forward. Which is why they lurch forward as the bus decelerates.
It is due to inertiaInertia is the resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion.
There is no such thing as "force of inertia". The passengers are thrown forward, maintaining their initial motion. This is an application of Newton's First Law, which states that an object in motion stays in motion unless acted upon a force. The force of the car brake is acted upon the car and not on the passengers. This is why the passengers continue to move forward for a second when the car stops.
Well... if something changes, it can't be called a constant. And the effects appear not at the speed of light, but when you approach it. What changes is: the time; distances in the direction of travel; the mass of the travelling object.
What is the advantage and this advantage of a forward reverse control of a motor
No. It depends on what other forces are acting on the object.
Earth can push and object forward with a reaction force
