What force causes a bike to slow down when you stop pedalling?
Friction causes the bike to slow down.
John pushes his bike along the sidewalk at a constant speed if he increase the force on the bike what happens?
If John increases the force on his bike, the bike will accelerate and move faster. This is in accordance with Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it.
What energy transformations occur in a bike going up and down a hill?
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.
Why is a bike considered a device that can convert energy?
A bike is considered a device that can convert energy because it allows a person to convert the energy from pedaling into kinetic energy to move the bike. As the pedals turn, the mechanical energy provided by the person is transferred to the wheels, propelling the bike forward.
What energy is used to pump up a bike?
The main energy source used to pump up a bike is human muscular energy. When pedaling, the rider applies force to the pedals, which turns the gears connected to the wheels, propelling the bike forward.
What is it called to roll down the hill on a bike without pedaling?
to roll down the hill on a bike without pedaling is called coast or coasting
What force causes a bike to slow down when you stop pedalling?
Friction causes the bike to slow down.
Why the pedaling important for riding a bike?
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.

What is a situation in which balanced forces are acting on a bike?
When a bike is traveling at a constant speed along a flat road, the forces acting on it are balanced. The force exerted by the rider pedaling forward is balanced by the resistive forces such as air resistance and friction. This balance of forces allows the bike to maintain a constant velocity.
Why does bicycle gradually slow down when you stop pedaling?
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.
Can you have a coaster brake and a cassette hub at the same time on a bike Like stopping the bike by pedaling backwards?
No because the bike would brake evry time so no
What changes when a bicyclist stops pedaling on a level road?
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.
How do you stop your pedal getting force backward while in a fakie on a bike?
You can either pedal backwards while riding fakie, or buy a freecoaster hub which doesn't require any sort of pedaling while you ride fakie.
