The phenomenon you're describing is explained by Newton's First Law of Motion, often referred to as the law of inertia. This law states that an object in motion will remain in motion unless acted upon by an external force. When the subway train stops suddenly, your body continues to move forward due to its inertia until an external force, like the train or a handhold, stops you.
Gravity maybe?
Standing passengers on a bus fall forward when it stops due to inertia. When the bus suddenly stops, the forward momentum of the passengers causes them to continue moving forward until they are stopped by a barrier or regain their balance.
When the bus suddenly stopped, several standing riders went flying forward. I enjoy flying a kite.
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 a car stops suddenly, your body continues to move forward due to inertia, which is the tendency of an object in motion to remain in motion unless acted upon by an external force. This is a consequence of Newton's First Law of Motion. The seatbelt and other restraints are designed to counteract this forward motion, helping to keep you safe during a sudden stop.
Inertia, which is the tendency of an object to resist changes in its motion. When a car stops suddenly, your body continues to move forward due to its inertia until an external force, such as the seatbelt or airbag, stops it.
Yes--because of Newton's first law, the passenger wishes to stay in its constant state of motion, which is standing still in this case. Hence, when the train starts to move forward, the passenger will want to stay at the point he/she was and will fall backwards.
When a car suddenly stops, your body continues moving forward due to inertia, which is the tendency of an object in motion to remain in motion unless acted upon by an external force. This principle is described by Newton's first law of motion. The seatbelt or other restraints in the car are what ultimately apply the necessary force to stop your forward motion and keep you safely in place. Without these restraints, you could be thrown forward, potentially causing injury.
Inertia
When a driver suddenly applies the brakes, the car decelerates rapidly, but your body continues moving forward due to inertia, the tendency of objects to maintain their state of motion. This forward movement happens because your body is not directly attached to the vehicle’s braking system. As a result, you experience a jerk as your body lags behind the car's sudden stop. This phenomenon is a basic principle of physics that explains how forces affect motion.
Inertia
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.
