00:00Why trains cannot stop quickly, know the physics behind it, understanding the physics behind
00:08train braking systems.
00:12Weight and momentum.
00:13A train's weight and speed significantly impact its momentum.
00:20Braking system activation time.
00:22Train braking systems require time to become fully effective.
00:28Train speed and stopping time.
00:30Higher train speeds necessitate longer stopping times.
00:36Braking distance challenges.
00:38Minimum braking distance can be exceeded before a driver reacts.
00:45Train length and momentum.
00:46A train's length contributes to its continued forward movement.
00:53Safety protocols and gradual stops.
00:55Safety protocols mandate gradual stops for passenger safety.
01:02Hard braking and derailment risk.
01:05Hard braking can be dangerous for passengers and cause derailment.
01:11Terrain and track visibility.
01:13Limited track visibility can hinder timely braking.
01:19Track conditions and friction.
01:21Track conditions affect wheel rail friction and stopping distance.
01:27Track grade and stopping difficulty.
01:29Stopping on inclined tracks presents additional challenges.
01:36Load distribution and braking.
01:38Cargo load distribution affects stability and braking efficiency.
