Most high speed trains are electrically driven, deriving power from an overhead rail via a pantograph. The train has considerable aerodynamic drag, so that if drive to the wheels is reduced, it will slow down.
Thus, if you add power it goes faster, if you reduce power it slows down. This can be done manually, or by a computer.

What factors affect the drag force that acts on a high speed train?
The main factors that affect the drag force on a high-speed train include the train's speed, shape and design of the train, surface roughness of the train's exterior, and the air density through which the train is moving. Additionally, environmental conditions such as wind speed and direction can also impact the drag force.
What factors affect the drag force that acts on high speed train?
Factors affecting drag force on a high-speed train include shape/design of the train, speed of the train, air density, cross-sectional area exposed to the airflow, and surface roughness of the train. Additionally, factors like temperature and humidity can also influence drag force.
How fast cane a europen high speed train travel?
European high speed trains can reach speeds of up to 300–350 km/h (186–217 mph) on dedicated high-speed railway lines.
How can the concept of momentum compare to a slow moving train and a high speed bullet?
Momentum is the product of an object's mass and velocity. A high-speed bullet has more momentum than a slow moving train because the bullet has a smaller mass but much higher velocity. This means the bullet can have more impact and be harder to stop compared to the train, even though the train has more mass.
If a person in a train moving at high speeds threw a ball straight into the air would the ball continue at the same speed as the thrower or would it travel a different speed?
The ball would continue to move at the same speed as the train in the horizontal direction, but its vertical speed would be affected by gravity. The overall motion of the ball would be a combination of the horizontal motion at the speed of the train and the vertical motion due to gravity.

What are the differences Between Japanese Shinkansens and European High Speed Trains in terms of how the train is controlled?
The difference between Japanese Shinkansens and European High Speed Trains is that the European High Speed Trains make use of European EC Directive 96/48 while the Japanese Shinkansens use an ATC (Automatic Train Control) system.
