to roll down the hill on a bike without pedaling is called coast or coasting
It's called coasting
Of course! That is, if you receive some other force such as a vehicle towing/pulling you up the hill, or someone pushing you up the hill whilst you sit on the bike. Otherwise, the answer is no, since opposing gravity requires force.
If you coast on a downhill slope you can ride a bike without pedaling, but otherwise pedaling is the only propelling force that a bike has, so you can't go anywhere without doing it.
Coasting
COAST!
Coast
Friction causes the bike to slow down.
Because unless you have a hill to coast down, or a really strong tailwind, you need to pedal to provide a force that can push the bike forward.
When a bicyclist stops pedaling on a level road, the bike will gradually slow down due to rolling resistance from the tires and air resistance. The momentum of the bike will keep it moving for a short distance, but eventually, it will come to a complete stop.
Coasting down a hill on a bike is when you ride without pedaling, using the momentum gained from going downhill to keep moving forward. It allows you to enjoy a break and conserve energy while still moving. It can be a fun and exhilarating experience, but it's important to maintain control and be aware of your surroundings for safety.
When you stop pedaling a bicycle, it gradually slows down due to several factors. Friction from the ground and air resistance act as opposing forces, gradually reducing the bike's speed. The bike's momentum also plays a role, as it takes time for the momentum to dissipate.
To roll down a hill on a bike without pedaling, you can coast by lifting your feet off the pedals and using your body weight to control your speed and balance. Keep your feet close to the ground for added stability, and use the brakes as needed to control your speed. Make sure to stay alert and be prepared to react to any obstacles or changes in terrain.
Well that happens because of 2 things:gravity and friction.When you stop pedaling it keeps going because the gravity is causing it to keep going or there is not much friction.It starts to slow down when the friction is enough.
Pedaling harder, rid excess material(weighs down bike), and angling your body into 60 degrees so there is less air resistance.
When a bike goes up a hill, mechanical energy from pedaling is converted to gravitational potential energy as the bike gains height. When the bike goes down the hill, the gravitational potential energy is converted to kinetic energy as the bike accelerates. Frictional forces also convert some of the energy to heat.
The brake pads against the wheel rims or disc rotor are the main components on a bike that use friction to slow down or stop the bike. Additionally, the tires gripping the road surface while pedaling or cornering also rely on friction to provide traction.
The force applied by a cyclist is called pedaling force or pedal force. This force is generated by pushing down on the pedals to propel the bicycle forward.
The energy of your motion transformed into other forms of energy, such as heat and sound, due to factors like friction between the bike's tires and the road. Kinetic energy from your forward motion was converted into kinetic energy between the tires and road, as well as heat energy due to friction, causing the bike to slow down and eventually stop.
