When we brake, the weight of the vehicle shifts?

When a vehicle brakes, the dynamics of weight transfer occur primarily due to the deceleration of the vehicle. As the brakes are applied, the forward momentum of the vehicle causes the weight to shift toward the front. This is a natural consequence of physics, where the inertia of the vehicle resists the change in motion.

The front wheels bear more weight during braking, which enhances traction. This is critical for maintaining control and stability, as the front tires play a significant role in steering and stopping. Understanding this shift in weight is essential for safe driving practices and helps drivers anticipate how their vehicle will respond when they brake suddenly or gradually.

The movement of weight to the front is also why brake systems are designed with this behavior in mind, allowing for optimal performance. The other options do not accurately reflect the physics of vehicle dynamics during braking.
