No the drill's friction against a tooth (enamel) is not harmful. If this procedure was harmful then there wouldn't be these people who wear white scrubs and make a ton of money to see teeth all day,,,, you know they call them (Dentist!!!!). Just kidding... I like to have fun. but no harm is done... They would not allow this in dentistry if it were harmful to you, (95% of procedures are having to use a drill one way or another... Aunt Laura
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.
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.
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
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.

Helpful Friction.
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.
If you need help I recommend you type in the specific question you need help with
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. Friction is not helpful in situations like when you are pulling something heavy. Some of the energy you are putting into pulling is going into heat from kinetic friction and making your job more difficult.
Yes, friction CAN be harmful, depending on where it occurs. If you'd fall and scrub your knee, that's harmful friction. IF your shoes are chafing and yopu get a blister, that's harmful friction. In a machine, if a bearing becomes warm, that's harmful friction.
Friction is helpful as it allows us to walk, hold objects, and write. It also helps stop vehicles and machines by providing traction. However, friction can be harmful as it causes wear and tear on moving parts, reduces speed in vehicles, and can cause injuries when there is too much resistance.
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.
