Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.
Will frictional force depends on mass and density?
Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
Does the frictional force depend on the type of surface in contact?
Yes. Different substances have a different coefficient of friction.
Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.
What factor does the limiting value of the force of the static friction depend?
limiting friction is force of friction when a body slides over the surface of another body
What does strength of the force of gravity depend on?
on chet
What force is used to slow down a bike?
strength New: The force of friction. When you apply the brakes, they grip the wheel, creating friction, which slows down the spinning.
A force that resists motion?
friction resistance opposition impedance These all have a slightly different connotation and depend on the type of force under consideration.
The strength of a force is measured in this SI unit?
That's going to depend on what you mean by "strength". There is strength of faith, strength of opinion, strength of character, strength of an odor, strength of a received signal, and physical strength, just to mention a few that I can think of right now. To pick an easy one: If you mean the strength to lift a weight, then that could be measured in units of force. In order to bench-press 200 pounds, you need to be able to exert 200 pounds of upward force while lying on your back.
What are the two factors that determine the strength of the force friction between two sliding object?
no
What are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
Will frictional force depends on mass and density?
Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
If friction isn't dependent on surface area but only on the coefficient of friction between two surfaces and the reaction force then why do racing cars use bigger tires with greater area?
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
