Why is friction harmful while driving a car in the winter?
Friction can be harmful or helpful when driving, no matter what time of year. For instance it is helpful when breaking and it is harmful between bearing surfaces. The loss of friction between the tyres and the road during winter can be disastrous.
How is friction harmful while playing football in paragraph?
Friction can be harmful while playing football as it can lead to skin abrasions, blisters, and discomfort when running or changing directions quickly. Excessive friction between the football and the playing surface can also affect ball control and passing accuracy. Additionally, friction between players during physical contact can increase the risk of injuries such as sprains or strains.
What are the differences between useful and harmful friction?
The type of friction that benefits in some or other way like smooth running of vehicles on the road is called Useful Friction whereas other wherein it becomes a causative factor for wear and tear or damage to the object in question.
How does a bicycle use force gravity and friction?
A bicycle uses gravity by pulling the rider and the bike downwards, helping to propel the bike forward when going downhill or gaining speed. Friction between the tires and the ground allows the bike to grip the road and move forward, while also providing stability when turning or braking. The force generated by pedaling provides the necessary propulsion to overcome friction and continue moving forward.
When you bring your bicycle to a stop where does the kinetic energy it had go?
When you bring your bicycle to a stop, the kinetic energy is converted into other forms of energy, such as heat and sound. Friction between the bike's wheels and the ground dissipates the kinetic energy as heat, while the braking mechanism may also convert some of it into sound energy.
What are two ways friction can be be harmful while riding a bicycle?
In the bearings and in the tires. All it does there is turn into heat - and we can't use that for going forward.
How friction influenced the invention of the bicycle?
Tires, grips, pedals and brakes needs to have high friction, while all rotating parts needs to have low friction.
How does the revoshift friction system enhance the performance of a bicycle?
The revoshift friction system enhances a bicycle's performance by allowing for smooth and precise gear changes, resulting in improved control and efficiency while riding.

How does low air pressure in bicycle tires reduce the efficiency of the bicycle?
Flabby tyres produce more friction with the road.Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)
How does braking stop a bicycle?
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 stopsA stationary part is brought into contact with a rotating part. The resulting friction slows the bike down.

How and where is friction used in a bicycle?
Friction occurs in any relative motion. The rougher the surfaces in contact, the higher the friction between them. In a bicycle, friction is what makes it move when you pedal. There is friction between your foot/footwear and the pedal. That is why a bicycle pedal is rarely a smooth surface. Your foot shouldn't slip off it. The handlebars are also rough so that the friction prevent your hands from slipping off while riding. The seat is made of rubber or a similar material usually as it is rougher and softer than a metal or wood, reducing sliding on the seat. Friction between the tires and the ground is what makes the bicycle move. That is the reason why a worn out tire is more likely to skid on the ground, and also the reason why mountain bikes and bikes built for rougher terrain have deeper and better designed grooves on their wheels to create more friction and thus more traction.
What are the differences between friction and index shifting in bicycle gears?
Friction shifting in bicycle gears involves manually moving the gear lever to adjust the position of the chain on the sprockets, while index shifting uses a mechanism that clicks into preset positions for more precise and consistent gear changes. Friction shifting requires more skill and finesse to find the right gear, while index shifting offers quicker and more reliable gear changes.
What are the differences between useful and harmful friction?

How does a friction effect with bicycling?
friction makes riding a bike possible. When the tire presses on the ground, friction acts against the rotation of the tire, fixing the lowest point of the wheel on the floor. This force is transmitted to the axel of the wheel and is what propels the bicycle forwards.
Does it take more force to push a car or skateboard?
first of all the car is heavier than a bicycle. and a bicycle only has 2 thin wheels while a car has 4 broad wheels. thus there is more contact. hence there is more friction.
