Yes, heavier cars generally take longer to stop compared to lighter cars, assuming all other factors are equal. This is due to the greater momentum that heavier vehicles possess, which requires more force to decelerate. Additionally, heavier cars may have larger braking distances because of the increased mass that needs to be slowed down. However, factors such as brake system efficiency, tire grip, and road conditions also play significant roles in stopping distance.
Trucks take longer to stop than passenger cars.
Yes. Because the truck is heavier.
Depends upon conditions. Studies show that Most cars with ABS stop faster on wet and even dry pavement. However ABS cars take longer to stop on ice, snow, and gravel. Personally I really like them in rain, and CANNOT STAND THEM on snow/gravel.
Yes...a heavy car will accelerate slower, take longer to stop and ultimately have a lower top speed then if it were lighter. The first two are correct but the last is wrong. The simple fact that the car IS heavier means there will be more kinetic energy achieved over a longer time to very fast top speed usually occur in heavier equipped cars with the correct type of engine. The fastest cars (the speed record holders) start slowly but gain very fast speed weigh in and more than 15,000 lbs. That is 3 to 5 times heavier than the typical car.
WHY!It is because the ice makes the friction between the tires and the pavementgreater.
It can take up to three times longer to stop a vehicle in wet conditions.
More mass means more inertia - more difficult to change the velocity. Newton's Second Law: force = mass x acceleration, means that for more mass, you need more force to get the same acceleration. Alternatively (if you save for acceleration), if you increase the mass, the same force will produce less acceleration. Note: It is the MASS of the object, not its WEIGHT, that is relevant here. On Earth, though, weight is proportional to the mass.

yes
If the car hit a solid wall, it would stop in a small fraction of a second.
Yes, the faster you are moving the longer it will take to stop.
Depending upon the number of cars and load being transported, a train can take up to 150 seconds to stop.
