Final answer:
The term that describes stopping fast without breaking is deceleration.
Step-by-step explanation:
Deceleration is the opposite of acceleration. It refers to the decrease in velocity or speed of an object over time. When an object decelerates, it is slowing down. This can be achieved by applying a force in the opposite direction of the motion.
For example, when a car is moving at a high speed and the driver suddenly releases the accelerator pedal, the car decelerates as it slows down. Similarly, in sports, when a player abruptly stops running, they decelerate to come to a halt.
