Verified step by step guidance

1. Understand the terminology related to vehicle motion and braking: the 'braking point' is the moment when the driver applies the brakes and the vehicle starts to decelerate.
2. Recognize that 'acceleration point' refers to when the vehicle begins to speed up, which is not related to braking.
3. Know that 'reaction distance' is the distance the vehicle travels during the driver's reaction time before the brakes are applied.
4. Identify that 'stopping distance' is the total distance the vehicle travels from the moment the driver perceives the need to stop until the vehicle comes to a complete halt.
5. Conclude that the correct term for the point where the brakes are first applied and the vehicle begins to slow down is the 'braking point'.
