Almost always. Unless the airplane happens to be an ultralight, or the car happens to be a Hummer.
The engine and other components are at the front of a vehicle. This makes the front heavier and is why tires wear quicker in front.
engine
The question is not weight, it is the rolling resistance of the compartments, AND the traction of the engine on the rails. Think of this- I cannot pick up a car, but on level ground I can PUSH a car. And I weigh far less than my car.
A car?
train, airplane.
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.
The water cooled engine will typically be heavier, because you have to add in the water pump, the radiator and the water/coolant. The engine block itself may be lighter as there are passages drilled out for the water/coolant to flow through.
well just imagine that you are building a car, or a train or an airplane and the metal you use for something starts to rust, if that's near the engine or something that leads to the engine than it could put set the car a light.
It depends on the type of rocket.
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).
Yes. If it is heavy it will go slower than a light toy car, if it is light it will movefaster than a heavier car.
You have to know the answer already. The large truck is heavier of course.
