In general, friction acts to prevent objects in contact with each other from moving with respect to each other. Friction keeps your furniture where you place it. The friction between your feet [or shoes] and the ground enables you to walk. When you apply the brakes in a car, friction causes the wheels to stop rotating . Friction holds a screw or nail into a board and a nut onto a bolt. Friction between your fingers and an object allows you to pick it up. Friction is proportional to surface roughness. A measurement of the force needed to overcome friction can be used as an indicator of a surface's roughness/smoothness.
When friction is used to reduce relative motion (or to get objects moving), a portion of energy needed to do so is dissipated in the form of heat. This is why a car's brakes get hot and why a nail pulled out of a board can feel warm. Usually, this heat is just a waste byproduct, but it can be useful. The friction of rubbing your hands together will warm them, and the heat of driving a nail into a board can be used to temporarily melt the adhesive on 'cement coated' nails.

What is boundary friction?
boundary friction
How does friction make friction?
when 2 surfaces rube or slide together the more smooth the less friction
What new tools of genetic engineering allow us to manipulate directly?
DNA
What is Friction in induction motor?
Friction is present at the motor shaft and also in various parts of the load. The friction torque is equivalent value of various friction torques referred to the motor shaft.
What are the causes of sliding friction?
For example the cause of sliding friction of two materials is when the stress between the Materials is not equal to zero
What does WA mean in science to do with friction?
wont allow
Why do you need friction?
we need friction because if there were no friction the objects around us will slide
Does friction play a necessary role in a roller?
It keeps the roller down and creates friction to allow the roller to move.
More advantages of friction?
friction helps us to move
How does Friction Help Us?
Friction helps us by letting us grasp things so they won't fall. Without friction you can expect to have more car accidents, and a lot of random people falling because friction helps us walk. Also airplanes in a way use friction to fly. no slaking in class
What does all types of frictions do?
Friction act on us every day. Types of Friction: 1) Sliding friction 2) Rolling friction 3) Static friction 4) Fluid friction
What thing can you use to help us overcome friction?
wheels overcome friction
What force prevents people from sliding when they walk?
Friction. Gravity holds us to the floor, friction keeps us from slipping.
How do forces like friction help us?
friction slows us down if it wasn't for friction everyone would be slipping everywhere
How does air resistance allow the car to go faster?
The air creates friction, just like the ground. With less friction, the less pushing the car back.
How does friction hurt us?
Ratchetgirl! :d
How does friction affect us?
