describe how friction helps and how it creates a problem when you cycle
Answers
Helps:it gives you to grip and pedal the cycle moves properly without slipping.
Problem :it feels hard to cylce and I lose a lot of energy.
Fiction plays an important part in our everyday lives. The reason why we are able to walk is due to friction. As we push the ground back, our feet are moving across a rough surface with its surface molecules and crevices that are shaped so that the surface molecules of the object and of the plane fit, creating friction and helping us not fall. If there was no friction, roughness in surfaces, the ground would be as smooth as an ice skating ring. Our feet will have no other surface molecule to adhere to which will make us not grounded and fall.
As friction helps us walk, friction also helps cars move forward. As a car’s tires hit the asphalt, the tires’ surface molecules are adhering to the surface molecules of the asphalt, making the car able to push off the ground and the ground able to push the car forward. However, the frictional force on a car on a level surface is different from the fictional force on a car on an inclined plane. The force of friction is dependent on the coefficient of friction, the roughness of the surface, and the normal force (f=uN). On an inclined plane, the normal force decreases. As the normal force decreases, the frictional force decreases as well. Different planes and surfaces change the frictional force
