to roll down the hill on a bike without pedaling is called coast or coasting
Friction causes the bike to slow down.
Pedal rotation on a push bike is commonly referred to as "pedaling." This action involves the cyclist pushing down on the pedals with their feet to propel the bike forward. The rotational movement of the pedals is transferred through the drivetrain to turn the bike's wheels.
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.
The bike seat moves up and down by adjusting the seat post, which is a metal tube that can be raised or lowered within the bike frame. This allows the rider to find the most comfortable height for their legs while pedaling.
Pedaling backwards on a bicycle involves rotating the pedals in the opposite direction of normal pedaling. This technique can be used to slow down or stop the bike, as well as to help maintain balance at low speeds. It requires coordination and practice to master.
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.
A coaster brake is a type of brake on a bike that is activated by pedaling backward. It differs from other types of brakes, such as hand brakes, because it does not require the use of hands to operate. Instead, the rider can slow down or stop by simply pedaling in reverse.
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.
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.
Pedaling harder, rid excess material(weighs down bike), and angling your body into 60 degrees so there is less air resistance.
