Deceleration rate is the rate at which an object slows down or decreases in speed over time.
Deceleration rate is typically measured in meters per second squared (m/s²) or miles per hour per second (mph/s).
This depends on the specific cars being compared. It is not necessarily true that a larger or more expensive car will have a greater deceleration rate than a smaller or less expensive car.
Some factors that can affect a car's deceleration rate include the condition of the brakes, the weight of the car, the type of tires, and the road surface.
A car with a higher deceleration rate can come to a stop more quickly, which can be advantageous in emergency situations. However, a car with a very high deceleration rate can also be more difficult to control and may cause discomfort or injury to passengers. It is important for drivers to understand and be able to control their car's deceleration rate for safe driving.
