Experimental methods and steps to explore the influencing factors of bicycle braking distance;

(a) The relationship between braking distance and speed,

Test: When driving at a speed of 5 meters per second, it takes 3 seconds from braking to complete stop, and it is 7 meters forward.

When driving at a speed of 4 meters per second, it takes 2 seconds from braking to complete stop, and it takes 4 meters to move forward.

(2) The relationship between braking distance and load.

Test: When riding a single person, it takes 2 seconds to stop at a speed of 4 meters per second, and it takes 4 meters to go forward.

When two people ride (one on the back), they also travel at a speed of 4 meters per second. It takes 3 seconds from braking to a complete stop, and they rush 8 meters forward.

Report: Experiments show that when riding a bicycle, the higher the speed, the harder it is to brake. Similarly, double riding is more difficult to brake than single riding. Therefore, in order to ensure traffic safety, riding a bicycle on the highway must be single and driven at a low speed.
