Relative speed tells us the difference in speed between two objects moving in the same direction. We can calculate this by simply subtracting the speed of one object from the speed of the other.
Overtaking:
When two trains are moving in the same direction and on a direct line, the one with the higher relative speed will eventually overtake the other.
The relative speed will be the larger of the two speeds.
This happens because the object with the higher speed is essentially moving "faster" than the object with the lower speed.
Crossing:
When two trains are moving in the same direction but on different lines, the one with the higher relative speed will need to cross the other to pass.
The relative speed will be the smaller of the two speeds.
This happens because the object with the lower speed will have to "slow down" to avoid colliding with the object with the higher speed.
Examples:
If Train A is traveling at 60 km/h and Train B is traveling at 40 km/h, then the relative speed would be 20 km/h.
If Train A is traveling at 80 km/h and Train B is traveling at 60 km/h, then the relative speed would be 20 km/h.
Important Points:
Relative speed is always greater than or equal to the speed of the slower object.
It is important in traffic, transportation, and navigation to understand relative speeds.
Relative speed can be calculated with addition or subtraction
