Friction can be both harmful and helpful. Without friction the tires of the bike could not push against the ground to move forward, and the brakes would not stop the bike. However, friction can cause parts of the bike and the tires to wear down. Also, to overcome the friction between the tires and the road you need to pedal harder to go faster.
friction is helpful to stop the bike when you put on the brakes but it may be harmful by slowing your speed down. and if you hit the brakes hard at a sudden moment, you could tumble or flip

Name some ways that friction can be helpful and some ways it is harmful?
Friction is helpful in situations like when you are standing on a hillside. Static friction between your shoes and the surface are stopping you from slipping.

Name two ways that friction is harmful?
The two ways that friction is harmful is that it causes wear and tear of the parts and there is also causes abrasion on surfaces. However, frictions is also useful in various ways like braking when riding a bike and so on.In elevator systems, it is harmful to motor and machine bearings, causes wear. on elevator rails that elevator rides on ,the guide shoes wear and need constant lubrication, unless they use more modern roller guides.
How does riding your bike make the world a greener place?
