Lots of friction is needed in car brakes to slow down or stop the vehicle effectively, in shoe soles to provide traction and prevent slipping, and in rock climbing equipment to secure climbers on the rock surface.
when 2 surfaces rube or slide together the more smooth the less friction
Friction definitely is a force that can make things easier. Stopping a car for example is made easier by friction.
Friction is important because without friction we would be sliding and slipping everywhere as friction slows down and stops things. Friction occurs when two things touch or make contact.
The force that acts between two sticks when they are rubbed together is friction. Friction is a force that opposes the relative motion between two surfaces in contact. When the sticks are rubbed together, the friction force resists their sliding motion and generates heat, causing the sticks to heat up and potentially ignite if the temperature becomes high enough.
Rubbing your hands together generates friction, which creates heat. This can be useful for warming up your hands on a cold day.
Oxygen and friction.
lots of things
To increase friction, you can roughen the surfaces in contact or increase the force pressing the surfaces together. To decrease friction, you can make the surfaces smoother or reduce the force pressing the surfaces together.
Sell lots of things at high prices
To increase friction, you can increase the weight pressing the surfaces together, roughen the surfaces in contact, or use a material with higher friction properties.
friction is rubbing two items together to make friction without is your breaks on the car they would be useless friction causes heat - Brenner Fodt age 12
