Because if there wasn't any friction, nobody could be stopped. You wouldn't be able to Rollerblade, or play almost any sports.
If there was no friction, you wouldn't be able to hear a lot of Musical Instruments!
What else can I help you with?
What are 3 types of kinetic friction?
1. Our cars would get much better gas mileage without tire and air friction. 2. There would be no more skinned knees if friction didn't exist. (Like when you are skating or playing football.) 3. We wouldn't have to worry about clothes chaffing us in dry weather if there were no friction. 4. We could do some pretty amazing dance moves without friction. (The Electric Slide would last forever....) 5. Our shoes would last a lot longer without friction.
Which friction has least value option sliding friction static friction rolling friction Air friction?
i think it it rolling friction
How can friction be helpful or harmful?
Both! Here is a list: Helpful: 1. We need it to brake/stop our cars 2. We need it to fly in airplanes. (The friction of air on the wings cause the plane to stay in the air) 3. We would slip and fall if there were no friction between the ground and our shoes 4. We wouldn't be able to turn a doorknob without friction. (Our hand would just slide off of it.) 5. We can warm our bodies by friction. (When people get cold, they can rub thier chest, arms and legs to create warmth by friction) Harmful: 1. Our cars would get much better gas mileage without tire and air friction. 2. There would be no more skinned knees if friction didn't exist. (Like when you are playing soccer or football.) 3. We wouldn't have to worry about clothes chaffing us in dry weather if there were no friction. 4. We could do some pretty amazing dance moves without friction. 5. Our shoes would last a lot longer without friction Hope this helped(:
Which friction is greater sliding friction or static friction?
Static friction
Which kind of friction requires more force to overcome rolling friction friction or sliding friction?
Sliding Friction
What are the 2kinds of friction?
The two types of friction are static friction and kinetic friction. Static friction occurs when two surfaces are at rest relative to each other, while kinetic friction occurs when two surfaces are in motion relative to each other.
4 types of friction and give an example of each?
Rolling Friction, Static Friction, Sliding Friction, & fluid Friction
What is the plural of friction?
the plural form of friction is friction
Name the three types of friction?
Three types of friction are : 1. Kinetic friction :Friction that arises between surfaces in relative motion. 2. Static friction :Friction that acts between surfaces at rest with respect to each other 3. Rolling friction : Friction that occurs when an object rolls over a surface. Static, sliding, rolling.
How does Michael Jackson spin for so long?
it's all about friction and air resistance and it helped that he was an amazing dancer aswell. this video on youtube shows a guy doing it and how he does it: http://www.youtube.com/watch?v=RhSP7jC7q1g
Is static friction the same as starting friction?
Yes, look at "what is static friction?" Static friction is also known as starting friction.
What are the three types of friction and when does each apply?
There are three types of friction, static friction, rolling friction, and sliding friction. Static friction is friction between two surfaces that aren't moving relatively to each other. Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
