Why do you feel a jerk when a train beings to move?
Because the train is going 60mph and your going 0mph so the train is kind of pushing u through space but eventually your going 60mph so it goes away :D
Why does a speeding bullet and a fact moving train have so much force?
cause
Why does a moving train have so much force?
Sp it can get places on time and make it up hills.
If you are moving to the front of a moving train are you moving faster than the train relative to the earth?
Yes if the train is moving forward, you are moving at the train speed + walking speed relative to the tracks.
What is pseudo force-?
AnswerIn a closed moving train, moving with uniform velocity with respect to an observer on a station, the person in the train - here after we shall denote the person by the symbol A- will not know that he is moving.A bob suspended by as string from the ceiling of the train will be vertical to the floor of the train.Suppose the train now begins to accelerate. The bob will turn through an angle θ to the vertical. Since the train is a close one, A will infer from this this change in the vertical direction that his train is accelerating. He can calculate the acceleration from the angle and hence he will apply a force equal to mass times this acceleration to all the objects in his train.This force is not the result of reaction force as far as A is concerned To apply Newton's laws of motion which is for inertial frames of reference, A applies this force to all objects in his train and thus makes his frame equivalent to an inertial frame.This force which is not as a result of action reaction force [ with respect to A] is called pseudo force.
Is it possible for a train to have less momentum than a squirrel?
Momentum is a measure of the force that a moving object has (due to its movement).It is in direct proportion to both the object's mass and velocity. This means a higher mass, or a higher velocity means a higher momentum.Momentum = mass * velocity (p = mv)The mass of a train is vastly more than that of a squirrel.Therefore the only time that a train would have less momentum is when it was not moving, compared to a squirrel that was moving. As soon as a train moves its momentum will be greater.(You can think of it this way: you could overcome the force of a moving squirrel with your hand, but there is no way you could stop a train this way no matter how slowly it was moving.)
If a train is traveling at 60mph what time is lunch time near a box factory?
midday, 12 pm. Because the speed of the train is irrelevant to lunchtime
Why does a stationary train appear to be moving?
Because there's no such thing as "really" stationary or "really" moving. If the distance between a point on one train and a point on the other train is changing, then a person on either train says that the other train is moving, and both of them are correct. A "stationary" train only appears to be moving if the train you're on is moving relative to that one.
What is the minimum distance required to stop the train?
This depends upon the type of train, its tonnage. and the speed it is travelling. Passenger trains can stop much faster than a freight train. A passenger train at normal speeds of 60mph to 110 mph can be stopped in well under a mile, minimum distance as short as 2500 feet. A heavy freight train traveling at 40mph can take nearly 2 miles to stop.
Is there a fluctuation of voltage in a moving train?
Yes, there is a fluctuation of voltage in a moving train
Can a large mass moving at high velocity accelerate more?
Any object with mass can be accelerated to a higher velocity, no matter what its current velocity is. All that is required is a force to further propel the object. For example, if a train (mass = 100 tons) moving at 100 miles per hour was hit from behind by a car (moving 200 miles per hour; mass = 1 ton), the train's resulting speed from the collision would be higher than its original 100 miles per hour. The very heavy train would, indeed, accelerate.
You are seated in a train that is stopped at a station Use two different reference points to explain that the train can appear to be moving and not moving?
the person standing on the ground, the train is moving and the ground is stationary. but the person on the train looks he is stationary and the ground is moving.
