The train is heavier than the car is and the train has more things in the back. The train is heavier than the car is and the train has more things in the back.
It cant. They are connected. If the front car moved faster than the back car it would pull away from the back car.
During forward acceleration on any vehicle (front wheel drive or otherwise), more of the vehicles weight is transferred to the rear of the car, making the rear of the car heavier. This is undesirable in a front wheel drive car because there is less weight over the drive wheels to produce traction (causing the front wheels to spin)
A car?
It depends on the type of rocket.
The mass of a toy car will affect its speed. A lighter car will accelerate faster than a heavier car, assuming all other factors (such as the force applied) are constant. However, once in motion, a heavier car may maintain its speed better due to its inertia.
The engine can be in the front or the back of the car.
It takes longer for a heavier car to stop than it does a lighter one. Velocity increases as mass increases in turn increasing the time needed to stop (trains, semi trucks).
On the front of the car or the back.
Because they are used for steering and get more wear.
You have to know the answer already. The large truck is heavier of course.
The back, so it does not jerk forward and hit you.
