Why does a moving train have so much force?
A moving train has a lot of force because of its large mass and high speed. The force is generated by the train's engine, which converts fuel into energy to propel the train forward. This force allows the train to overcome friction and air resistance to maintain its speed.
Why does a speeding bullet and a fact moving train have so much force?
A speeding bullet and a fast-moving train have a lot of force because of their momentum. Momentum is the product of mass and velocity, so the greater the speed and mass of an object, the more force it has. In the case of a bullet or a train, their high velocity and mass result in a significant amount of force when they collide with another object.
How does a maglev train slow down?
Maglev trains slow down by adjusting the magnetic field generated by the track to create a resistance force that opposes the train's motion. This force acts as a braking mechanism, gradually reducing the train's speed until it comes to a stop. Additionally, regenerative braking, where the train's kinetic energy is converted back into electrical energy, can also help in slowing down the train.
Would someone walking toward the back the train have greater or lesser speed relative to yo?
Someone walking toward the back of the train would have a greater speed relative to you if you are stationary inside the train. This is because their speed would be the combination of their walking speed and the speed of the train moving forward.
What would an observer on the ground obtain for speed of a ball on a train?
Just add or subtract (depending on the direction) the speed of the ball (in relation to the train) to the speed of the train (in relation to the ground). The above assumes the speeds are not close to the speed of light; if they are, more complicated formulae are required.
Does gear train provide a force advantage or speed advantage and explain?
Gear Train Advantage Arnel Dela Cruz Does gear train provide a force advantage or speed advantage and explain? Make it shortly A gear train can provide a force advantage or a speed advantage, depending on the arrangement of the gears. When the input gear has a smaller radius than the output gear, the gear train provides a force advantage, as the output gear will rotate more slowly but with greater torque. This is known as a gear reduction. Conversely, when the input gear has a larger radius than the output gear, the gear train provides a speed advantage, as the output gear will rotate more quickly but with less torque. This is known as a gear increase or gear multiplier.
How does friction affect the velocity of a train?
Friction between the train wheels and the tracks can slow down the velocity of a train by converting its kinetic energy into heat. Higher friction can cause more resistance, which can decrease the train's velocity. Conversely, lower friction or well-lubricated tracks can reduce the impact of friction on the train's velocity.
How does the size of the gears in a gear train affect speed and force?
If the driving wheel has more number of teeth, and the driven wheel has less number of teeth then there will be a gain in SPEED .If the number of tooth in the driver is less in the driving wheel and there is more number of tooth in the driven wheel , there will be a gain in TORQUE.
What is the average Train stopping distance?
This question is complicated to answer. It depends on a number of factors. For one, it depends on what type of train it is. A freight train, for example, can take over 2 miles to completely stop. It also depends on what speed the train is going.
What is the reason to use speed of light in the theory of relativity?
The theory of relativity uses light speed as the theoretical maximum speed of all things in the universe. A question posed Einstein himself is as follows: "If I were on a train travelling at light speed and I walked from the rear to the front, would I not have exceeded light speed?" Einstein: "No, the force you placed on the train in order to move foreward would have slowed the train a small amount, meaning that you would not exceed light speed"
Why does a speeding bullet and a train have so much force?
Each of those items has large momentum and kinetic energy ... the bullet because of its high speed, and the train on account of its large mass.
Why it is casier to short or to stop a car than a train?
because car in size and in mass is lighter than a train so the fact that its weight can affect the force needed to stop it so its easy to stop a car than a train .
Why does a speeding bullet and a moving train have so much force?
Each of those items has large momentum and kinetic energy ... the bullet because of its high speed, and the train on account of its large mass.
How much does an electric train cost?
Many factors, such as size and power, affect the cost of an electric train set. In general, these sets cost anywhere from 60 dollars to nearly 300 dollars.
What is the name of the french high speed train?
train a grande vitesse is the name of the french high speed train
What is the name of the high-speed train in France?
High-speed train; 'Train Grande Vitesse' or, TGV for short
What is the net force on the different cars of a subway train that is traveling at constant velocity?
If anything is traveling at constant velocity, then the net force acting on it must be zero.+++Strictly, it is travelling at constant speed, not velocity, because you have not specified the directions of the train and the retarding forces acting on it.
