A truck, except possibly a small pickup truck, will have more mass (weight) than typical cars. This means that for a given velocity, it has more momentum (kinetic energy) that will have to be opposed or removed in order to reduce its speed. The braking systems will have to dissipate more energy to stop the vehicle, and even with larger brakes, they will have to be applied over more time and the truck will travel more distance before it stops. A large truck can also do much more damage if it hits another vehicle or obstruction.

Assuming the car and the bike are both traveling at the same speed and both have new brakes. The bike will stop faster than the car due to less momentum. Car is heavier, harder to get going fast, harder to stop fast.
The reason that it takes a moving truck a much longer time to stop than it takes a car to stop when the brakes are applied on both is because the truck weighs more. The more mass a vehicle has the longer it will take to stop.
Longer stopping distances. A passenger car may weigh 3,000 pounds. A large truck may weigh 90,000 pounds. It is much harder to stop.

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.
More weight behind the train therefore longer stopping time.

Because a truck is heavier than your car, it takes longer to stop than you do. If you drive closely ahead of a truck you are asking for trouble. If you have to stop suddenly, there is no way they are going to be able to stop as quickly as you, even if they see you stop. A truck may also roll right over you instead of just rear-ending you, and flatten your car like a pancake. Moral of the story - keep a safe distance from trucks!
Yes. Because the truck is heavier.
As trucks are generally heavier than cars they require a longer distance to stop.
Twice as long as a car. If the truck is loaded all that extra weight makes it harder to stop. If the truck is empty, the tires will probably be inflated to too-high air pressure to keep good contact with the ground, and they will skid easy. And a truck cannot swerve around an obstacle as well as a car, since trucks tip over easy.
