But since kinetic energy depends upon the square of the velocity, the higher car velocity matters much more than the lower mass. The car starts with a higher kinetic energy and thus requires more work to stop it. With a greater work, the force has to be applied over a larger distance. That's the explanation.

Why do Heavier Things take longer to stop?
Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.
Does a heavier car stop faster?
A heavy car has more inertia, but the heavier car weight results in more force between the tires and pavement. If the tires coefficient of friction was not affected by the load, or if the heavier car had different tires, it could stop in the same distance or even less distance as the lighter car.
How does the weight of a car affect the stopping distance?
The brake power required to stop a vehicle varies directly with its weight and the “square” of its speed. For example, if weight is doubled, stopping power must be doubled to stop in the same distance. If speed is doubled, stopping power must be increased four times to stop in the same distance.
Do heavier trucks stop faster?
The brakes, tires, springs and shock absorbers on heavy vehicles are designed to work best when the vehicle is fully loaded. A heavily loaded truck will take longer to stop than an empty truck.
Which do you think is more difficult to stop a loaded truck or a car running at the same speed as the truck Why do you think so?
A moving object can have a large momentum if it has a large mass, a high speed, or both. It is harder to stop a large truck than a small car when both are moving at the same speed. The truck has more momentum than the car. By momentum, we mean inertia in motion.
Does a heavy car go faster than a lighter car?
What's clear is that a lighter car will accelerate more or require less force to accelerate like a heavier car. ... As the acceleration is slower with a heavier car of the same power, you have to accelerate for longer (more time) to cover the same distance so you use more fuel.
Does stopping distance depend on mass?
The work required stop is proportional to mass. Distance to stop is proportional to the force. There are two coefficient of frictioncoefficient of friction: static and kinetic.
What can stop a moving car?
Options to Halt A Moving Vehicle
In order to do so, many departments utilize devices like push-bars or portable spike strips. The push-bar is common device mounted on the front of a cruiser and used to conduct a Pursuit Intervention Technique (PIT) on fleeing vehicles.
Does speed increases the distance required to stop?
The faster an object is moving, the longer the distance it takes to stop. If a vehicle's speed doubles, it needs about 4X's the distance to stop. ... If you increase the weight of an object, you will also need increase the amount distance needed to stop.
Does weight increase braking distance?
The weight of a car absolutely does affect it's braking distance. Most heavier cars have more robust brake systems than lighter ones so their braking distance can even be shorter than the light ones.
How does gravity affect total stopping distance?
How does gravity affect your vehicle? The force of gravity will cause your vehicle to speed up when going downhill, and slow down when going uphill. ... Traction enables your tires to grip to the road and control your vehicle. Without traction, your car would not be able to accelerate, stop, or turn.
