How are friction and air resistance different?
air resistance is different from friction because friction is more than one thing because there is many different types of friction air restance is one of those types of friction.
Friction and speed?
Speed is how fast something is moving. When to things are traveling at the same speed and rubbing together, they can cause friction.
Force opposing the movement of one surface over another?
friction
What is the force called the resists the movement of one surface past another surface called?
I'm not sure if you are talking about friction or not. Does this force produce heat? Friction, I think
In charging an object by friction which of the particles is transferred from one object to another?
electrons
What are friction materials?
friction materials are the one which help in inducing friction to a friction-less object, like brake lining on the brake shoe is used for inducing friction between the brake shoe and the inner rim of the wheel.
Example of ways increasing friction?
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
Materials can increase friction?
friction causes the object in motion to slow down and finally stop. The natural condition of an object that is in motion is to stay in motion. Only friction (the object in contact with another object at rest) will cause the object in motion to lose its motion.
Can you stop friction?
You can reduce it to a point it is not noticeable but can not eliminate it altogether. You can reduce friction through use of materials with lower coefficient of friction like PTFE or by changing the way the materials contact, say change a sliding one to a rotating one.
2 ways to increase friction?
find a materials with a high coefficient of static friction and use them against each other ( like rubber dry concrete ) and bound them to the object and the surface it rests on. Increase the normal force by adding mass on the object or applying a perpendicular force to the surface of the object.

How friction increases with weight?
yes, this is true when anyone increases our weight then no-one can't control oureself .( friction *weight).& increase the force .force is (torque*weight).hence friction increase with weight.
What is the effect of surface area on friction?
The increase in One increases the Other. What alters the friction effects between Surfaces is another matter.
What is friction and causes?
Friction is the pull between two or more objects that causes the objects to slow and eventually come to rest. There are many types of friction, such as air friction or surface friction, but all types of friction create a pull on one another.The primary causes of friction are surface roughness, the plowing effect and molecular adhesion. Surface roughness is when serious abrasion occurs due to the roughness of the materials in contact. The plowing effect involves deformations of the objects that cause resistance to movement when the materials are relatively soft. Adhesion refers to the molecular force that results from two materials brought into close contact with one another. To slide objects against each other, it is essential to break the adhesive bonds between them. According to recent scientific studies, friction occurs because of adhesive forces between materials. Ultra-smooth and sticky materials fall under the molecular adhesion category. There are varying degrees of surface roughness in solid materials. Even a smooth surface has small bumps that interfere with sliding motion. When the surfaces of two hard, solid materials are very rough, friction occurs due to the abrasion that happens when two objects slide against each other. Deformations are another cause of friction. Deformations form when soft materials deform under pressure and lead to an increase in resistance to motion. For example, when a person stands on a rug, he sinks in slightly, causing resistance as he drags his feet along the rug's surface. Resistive force is created, and friction occurs when the deformation becomes large.
How can you calculate friction?
One formula that is frequently used is: friction = mu x Fn, where mu (the Greek letter mu) is the coefficient of friction, and Fn is the normal force - the force that pushes the surfaces together, perpendicular to the surface. The coefficient of friction depends on the combination of materials; you can look it up in tables for different combinations of materials; or you can determine it experimentally.
What is one way to increase friction on an icy walk?
Use spiked soles or oversoles. This is what climbers do.
What are two ways friction can be increase?
one way is to make the surface rougher and another way is to increase the force pushing the surfaces together.
Why if you increase the angle of the inclined plane the acceleration of the trolley will increase?
If the angle is increased, the tangential component of the weight will increase, while the normal component - the one that causes friction - will decrease.
