Answer:
When a bicycle is moving upward a force is acting called friction which pulls the rider backward making it harder for the rider to move forward. When the rider is at a constant speed the forces are balanced (the same), when the bicycle is speeding up(accelerating) the forces are unbalanced.The force acting forward is greater. When the bicycle is slowing down the forces going upward and downward are the same, however the force acting backward is greater. The forces are unbalanced when slowing down. When at rest the forces are also balanced. So, overall , the only times when the force's are balanced is when they are either at a constant speed or at rest. The times when the forces that are unbalanced are when the bicycle is slowing down or speeding up.Generally, it is gravity that holds you down, some wind resistance depending on the clothing you wear (as baggy clothes can increase drag) this is why professional cyclists wear those dodgy suits.The frictional force between the tires and the road affects the speed of the bicycle. This force determines how well the tires grip the road surface and how efficiently the bike can accelerate or decelerate. Adjusting tire pressure, tread design, and road conditions can all impact this force.
The answer is friction!
You have two forces that act between the bicycle and the road. First there's friction.
With zero friction the bike would never get moving, it'd be left with the wheel spinning in the same place, or topple over.
As the wheel will roll along there can't really be too much friction between tire and road, unless the the tire actually sticks to the surface.
The next is gravity, pulling the bike against the surface. This pressure will cause the bicycle tire to deform. The more the wheel has to deform under the weight of the rider, the more energy will be lost in squashing the wheel as the bike rolls along.
it is actually friction......
Yes, gravity acts on a moving bicycle. Gravity pulls the bicycle and the rider toward the center of the Earth, influencing their motion. This force helps to keep the bicycle in contact with the ground and affects its acceleration and speed.
The amount of force pushing two surfaces together directly affects the magnitude of friction between them. More force increases the contact between surfaces, creating a greater frictional force. Conversely, less force reduces the frictional force between the surfaces.
Friction between the brake pads and the wheel rim or disc generates the force that slows down a bicycle when the brakes are applied. This friction converts the kinetic energy of the moving bicycle into heat, causing it to decelerate.
The force that makes a bicycle move forward is generated by the rider pushing the pedals, which rotates the chain connected to the wheels. This rotational force is transmitted to the wheels, causing them to turn and propel the bicycle forward. friction between the tires and the ground helps to convert this rotational force into linear motion.
The force that affects only objects with magnetic domains is the magnetic force. This force arises from the interactions between the magnetic fields of objects with magnetic domains and can attract or repel objects with magnetic properties.
What the brake lever does is that it use the action of the rider pulling on the lever into a force that can be used to slow the wheel(s) down by generating friction.
Because the size of the piston is rather small, so it doesn't take much force to generate the kind of pressures that bicycles need.
the magnetic force between the sun and the moon to the earth
A bicycle alone only use up space. But a human riding a bicycle will have to use force to get the bicycle to do anything, by pushing on the pedals, pulling on the handlebar ASO.
These are the hydrogen bonds between molecules.
MASS of both objects, and the DISTANCE between them.
The same as what affects the pull of other objects. The gravitational force between two objects depends on the mass of both objects, and on the distance between them.
The bicycle would have the greatest impact force.
They deform, first elastically then plastically.
Gravity: the force that pulls objects towards each other due to their mass. Electromagnetic force: the force responsible for interactions between charged particles. Frictional force: the resistance between two surfaces in contact when they move relative to each other.
The force of gravity between two objects is affected by their masses and the distance between their centers. The larger the masses of the objects, the greater the force of gravity, while increasing the distance between the objects decreases the force of gravity.
