Does deceleration feel like acceleration?

Deceleration can be understood as a form of acceleration in which an object's velocity decreases. It is considered a "special case" of acceleration because it involves a change in both magnitude and direction of the acceleration vector. Essentially, deceleration is the opposite of acceleration, resulting in a decrease in speed.

So, to clarify, deceleration and acceleration are not exactly the same sensation. While acceleration involves an increase in velocity, deceleration refers to a decrease in velocity. However, both concepts are rooted in the fundamental principles of kinematics and can be described by vectors that represent their magnitude and direction.

Is acceleration the same as deceleration?

Both cases of acceleration and deceleration are indistinguishable from each other in physical terms. Since there is no physical distinction between the two, humans are unable to perceive the difference. Rather, they can only sense the force being exerted and its direction, but are unable to determine whether it is accelerating or decelerating them.

What happens if a train is accelerating or decelerating?

When a passenger is in a train that is accelerating, they will have the same sensations as a passenger in the opposite direction in a decelerating train. This means that the passenger sitting and looking in the direction of motion will experience the same feelings as the driver. Similarly, the passenger sitting in the opposite direction will have the same sensations as a passenger in a train that is decelerating.

This principle holds true for both accelerating and decelerating trains. Therefore, the feelings experienced by passengers depend on the direction of motion, rather than the actual acceleration or deceleration of the train.
