Reference: AQA
A larger braking force produces a larger deceleration, and deceleration can be treated as negative acceleration.
Negative acceleration, occurring when an object slows down so that its change in velocity is negative.
Occurs when the velocity of an object decreases in magnitude, meaning the object is slowing down.
Occurs when an object slows down, so v is smaller than u and the acceleration is negative.
A negative value, such as −2 m/s², indicating that the object is slowing down.
A negative change in velocity, showing that the velocity has decreased.
