When you accelerate, the size of the front tire patch becomes____
Answer:
Larger
Explanation:
When a vehicle is accelerated, the weight of the vehicle and the driver is transferred to the front of the rear of the car.
This transferred weight is nothing but the additional weight that presses the car's suspension in the downward direction thereby affecting tire contact patch in the rear due to which the rear tires loses adhesion.
When you accelerate, the size of the front tire patch becomes larger.
It should be noted that to develop the power to accelerate quickly, an internal combustion engine is vital. When a vehicle is accelerated, the weight of the vehicle and that of the driver will be transferred to the front of the vehicle.
Therefore, when you accelerate, the size of the front tire patch becomes larger since the transferred weight is additional weight.
