How do you find the relative velocity of two trains?
When two bodies move in the same direction then the Relative Speed = Difference of Speeds i.e for a person a sitting in a train moving with a speed of 60 km/hr in the west direction, another train which is going towards the west with a speed of 40 km/hr, will appear to move at a Speed of (60-40) = 20 km/hr.
What is the motion of a train?
Train moving on a track follows a straight line, hence it undergoes rectilinear motion.
Why do places that we pass by train seem to be flying by?
while sitting in a moving train, they appear to move rapidly in the opposite direction because the line of sight changes very rapidly. On the other hand, distant objects such as trees, stars, etc. As a result, the line of sight does not change its direction rapidly.
What is relative velocity formula?
This velocity is computed according to the person as an observer inside the object. Mathematically, we nay say that the relative velocity will be the vector difference between the velocities of two objects. The relative velocity of A with respect to B= velocity of the body A – velocity of the body B.
Does the air on a train move?
It is all to do with air resistance and drag. The air inside the train is moving with the same speed as the train. The bee flying in the air inside the train is only moving at a small speed relative to the air in the train. However if we throw an object out of the train things are a bit different.
How is the travel in a train similar to the motions of the earth?
Answer: A gravity train is a theoretical means of transportation for purposes of commuting between two points on the surface of a sphere, by following a straight tunnel connecting the two points through the interior of the sphere.
Why do you think there was no water in the bathroom of the train?
Answer: There was no water in the bathroom of the train either because the passengers had used it up or because the water has been wasted due to leaky taps.
How is the velocity of a train relative to the ground?
If you’re riding in a train moving at 10 m/s east, this velocity is measured relative to the ground on which you’re traveling. However, if another train passes you at 15 m/s east, your velocity relative to this other train is different from your velocity relative to the ground.
Can a train travel faster than the speed of sound?
So if you put a speaker at the front of the 1,000 mph train, the sound waves will not depart the train at 1,700 mph. They cannot go faster than the speed of sound. This is the reason why planes traveling faster than the speed of sound create sonic booms.
Unfortunately, it can’t be quite right for high speeds! We know that for a flash of light going from the back of the train to the front, the speed of the light relative to the ground is exactly the same as its speed relative to the train, not 60 m.p.h. different.
What happens if you shoot a gun on a train moving as?
So what does this mean for our gun? If the gun shoots bullets at 1,000 mph, then the bullet will always move away from the gun at 1,000 mph. If you go to the front of a train that is moving at 1,000 mph and shoot the gun forward, the bullet will move away from you and the train at 1,000 mph, just as it would if the train were stopped.
