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.

Name two way that friction is harmful and two ways that friction is helpful when you are riding a bicycle?
Harmful: Friction can cause wear and tear on the bicycle's components, leading to maintenance issues. It can also make it harder to pedal efficiently, resulting in fatigue. Helpful: Friction between the tires and the road surface provides traction for stable riding. Friction between the brake pads and wheel rims helps to slow down or stop the bicycle effectively.
What are two way that friction is harmful and two ways that friction is helpful when you are riding a bike?
Friction is harmful on a bike by causing wear and tear on the components like brake pads and tires, leading to replacements. It can also make pedaling more difficult, resulting in increased fatigue for the rider. Friction is helpful on a bike by providing the necessary grip between the tires and the road for stability and control. It also aids in slowing down the bike when brakes are applied.
What is an example of harmful friction and describe how it can be reduced?
An example of harmful friction is when two metal surfaces rub together, causing wear and tear. This can be reduced by using lubricants like oil or grease to create a barrier between the surfaces, reducing the direct contact and minimizing friction.
What two ways can you change friction?
You can increase friction by increasing the roughness of a surface or by increasing the force pushing the surfaces together. You can decrease friction by using lubricants or reducing the contact area between the surfaces.
Two ways to reduce friction are to use what?
Two ways to reduce friction are to use lubricants, such as oil or grease, to create a smooth surface between moving parts. Another way is to use ball bearings or rollers to minimize the surface area in contact and reduce friction.
