friction is when two objects or air rubs together and creates heat which the slows the two objects down.
its like carpet burn your trousers rub against the carpet it slows you down and hurts!

∙ 15y agoFirst some vocabulary to understand, static = not moving and kinetic = moving (for the purpose of this explanation). There are microscopic ridges on all materials, when two materials are touching and not moving these ridges interlock to a degree. When you try and move these surfaces relative to each other it is harder to get them moving because you have to force these little ridges apart. A representation of this is called the coefficient of static friction. Once the surfaces are moving it is easier to keep them moving, and a similar representation of how hard it is to move these surfaces is called the coefficient of kinetic friction. Static friction is always larger than kinetic friction.

∙ 12y agoI'm not exactly sure what you mean. If you mean what does friction mean? then I can help.
Friction is the force between two things when they touch each other.

What is the charge on a piece of rubbed amber?
Friction strips electrons so the rubbed amber would take on a negative charge. Actually, friction causes charges to shift. Charges are indeed stripped from something, but they are collected up by something else. Amber does, indeed, become negatively charged by rubbing it with, say, fur. The phenomon is called triboelectric effect. And a link is provided.
What does it mean to say that water is potable?
It means you can safely drink it.
What is the molar mass of chloride?
you mean to say chlorine... and it 35.45g/mol
What does 10K mean inside a ring?
What does it mean if a ring say RS10K IN SIDE OF THE
What does HLD-CO FEL mean?
its to hard to say but look on you pc or labtop
What is the force that opposes motion?
Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
Kinetic frictions is the frictional force needed to start an object at rest into motion?
false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
What is the word for a force that opposes the motion of an object?
The opposing forces such as friction in case of solids and viscous force in case of fluids are always present in the natural world.a force can cause a resting object to move, or it can accelerate a moving object by changing the object's speed or direction.in a shorter way to say is frictionFriction
What friction is used when an object sits still?
Static friction resists an object from moving when at rest (still) with respect to the surface it is resting on or in contact with. Kinetic friction, or dynamic friction, (normally what we think of when we say 'friction') describes the friction that occurs when one body moves relative to another body and when both bodies are in contact with each other.
How does gravity impact friction?
With a fixed mass, if you say double the acceleration due to gravity, you would have to double the force to overcome friction.
The force that opposes the motion of an object?
Gravity. The inertia of an object will keep it moving until an opposing force stops it.Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
Does static or sliding friction keeps an object from moving when a force is applied?
i would say sliding
Would it be say that no force acts on a body moving on a perfectly smooth surface?
It would not be a perfect answer if I said yes because you did not assume that if the body was moving in vacumn. If its not, like for example it is moving on an ice block on the surface of the earth then the object still has gravity and the air friction acting on it. Even the molecules of the ice's surface attract the surface of that object it is in contact with. So if I say that the object is in space then it would be a incredibly correct answer to say yes, there are no force acting on the body.
What is the force you have to overcome to start an object moving called?
I have to guess either gravity or friction.If by that you mean a force that opposes the start of motion, then your force would be static friction.Static friction only occurs before an object starts moving, as opposed to kinetic friction which occurs when the objects is moving or sliding. The equation for static friction is: Ff = (coefficient of static friction) * FNInertia
What is Friction Force?
YES, YEA it is Yes it is a force. If not then we would be slipping around. What i have heard is that friction causes a pull in some ways. Say you slid a pencil on the floor with nothing in it's path. Now if you know what inetia (not a force) then you would know that the pencil would stop because of a outside force. And that force is friction. Friction had reduced the pencils speed when it rubbed together on the floor. Now if the pencil was givin more force when you pushed it and the floor was more slik then the pencil would have traveled alot more. This is because the force of friction is a less amount when one surface is smoother. I know this is a horrible explanation but this is what helps me think of the forces. And this is going to prove to my teacher that friction is a force and that inertia is not.
How will the coefficients of friction vary if you place standard mass on top?
It won't. Coeffecient of friction is based on the two materials involved (or more, e.g., if a lubricant is used) not on the mass placed on top. We can specify a coefficient of friction for, say, rubber sliding across concrete without ever saying HOW MUCH rubber slides across concrete. If we want to know FORCE of friction, then this is a different story. The force is based on the mass that's on top. On a flat surface, the force of friction equals the coefficient of friction times the weight of the object being dragged. The mass you are talking about would be included in calculating the force, but not in determining the coefficient of friction.
What happens to an object when a force acts on it over time?
If there is no counter-force (such as friction), in other words, if there is a NON-ZERO NET FORCE, the object will accelerate. That is to say, its velocity will change.
