What factors affect the drag force that acts on high speed train?
Air resistant
How does friction affect the velocity of a train?
friction will act in the opposite direction to the propulsion force driving the train. so it will cause a resistance and so limit the velocity
Which force stops a train when the brakes are applied?
Kinetic friction is the force that stops a train when the brakes are applied
How does mass affect an objects inertia?
A massive object has greater inertia. It requires more force to slow it down or change it's course. Example: It takes much more force to stop a train than it does to stop a car, only because the train has much greater mass.
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.
What factors affect the drag force that acts on high speed train?
Air resistant
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 will act in the opposite direction to the propulsion force driving the train. so it will cause a resistance and so limit the 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
