How does braking stop a bicycle?

Answer 1

Same as on a car. Applying the brakes means that something stationary is pressed against a moving part. This generates friction, which turns speed into heat.
It produces friction, because when the brake touches the rim of the bicycle, the bicycle slows down. (thats called friction) And after a while the bicycle stops
A stationary part is brought into contact with a rotating part. The resulting friction slows the bike down.

Answer 2

Newton's first law of motion tells us that something set in motion will stay in uniform motion until acted upon by an external force. So when you are coasting on a bicycle on a flat, level road, you would go on forever if there were no forces to slow you down.

.

Friction and wind resistance are the forces that slow you down. The friction of the gears and wheels convert some of the bicycle's kinetic energy into heat, and thus deplete the bicycle of its kinetic energy, and that slows you down.

.

While you are coasting on your bicycle, you are passing through the atmosphere - you are pushing the air out of the way. Newton's third law of motion says that for every action there is an equal and opposite reaction. So as you push the air out of the way, it pushes back with the same force, also causing you to slow down.

.

If there were no friction, and no atmosphere, you could coast forever on flat, level terrain, assuming you could survive.

Answer 3

Friction in bearings and axles, wind resistance and losses as the tire rubber is deformed as the tire rolls over the ground.

Answer 4

the force of the plane, air resistance, just plain friction, mechanical resistance

Answer 5

Braking stops a bicycle by applying friction to a rotating part connected to the wheel, making it turn slower thus slowing the bike.
