Friction Between Clothing & Giant Rock: 833 N & μ=4.58?

In summary, the conversation discusses the possibility of having a friction force of 833 N between clothing and a giant rock, with a coefficient of friction (μ) equal to 4.58. The participants question whether this value is too large and speculate on the factors that could affect it. They also mention their calculations for friction, mass, and acceleration, and how they found μ to be 4.58. While this value may seem high, there are no limitations in the laws of physics for it to be greater than 1. However, it may be abnormal for clothing and a rock to have such a high coefficient of friction.

Is it possible to have friction between clothing and a giant rock equal to 833 N? The μ would equal 4.58. Isn't it too big?

Why would the coefficient of friction need to be 4.58? Wouldn't it depend on how hard they're pressed together?

Well this is for a physics project and a lot of it depends on guessing. We found friction to be 833 N, mass to be 85 kg, acceleration to be -2.14 m/s^2 because the cartoon characters are decelerating as they hit the wall. Will all of this μ(ma)= Friction, we found μ to be 4.58. We are just wondering if 4.58 would be too big for μ.

Oh, ok.

4.58 would be large but there's nothing in the laws of physics (as far as I know) that limits the coefficient of friction. I know at least that it can be greater than 1, so 4.58 isn't completely crazy.

Between clothing and a rock though, it would certainly be abnormal (but perhaps not impossible)

Everyone one knows that 'cartoon characters' always present physics in a true and accurate manner.
 

Related to Friction Between Clothing & Giant Rock: 833 N & μ=4.58?

1. What is friction and how does it affect clothing and a giant rock?

Friction is a force that opposes the motion of objects when they come into contact with each other. In the case of clothing and a giant rock, friction can cause the clothing to rub against the rock, creating resistance and making it difficult to move the rock.

2. What factors determine the amount of friction between clothing and a giant rock?

The amount of friction between clothing and a giant rock is determined by the weight of the rock (833 N) and the coefficient of friction (μ=4.58). The weight of the rock determines the force of the friction, while the coefficient of friction measures the roughness of the surfaces in contact and their tendency to stick together.

3. How does the coefficient of friction affect the amount of force required to move the giant rock?

The coefficient of friction plays a significant role in the amount of force required to move the giant rock. A higher coefficient of friction (μ) means there is more resistance between the surfaces and more force is needed to overcome it. In this case, with a high μ of 4.58, a large amount of force (833 N) would be required to move the rock.

4. Can the friction between clothing and a giant rock be reduced?

Yes, there are ways to reduce the friction between clothing and a giant rock. One way is to lubricate the surfaces, such as using oil or grease. Another way is to use a different material for the clothing, such as a slippery fabric, to reduce the roughness of the surfaces in contact.

5. How does the angle of incline affect the friction between clothing and a giant rock?

The angle of incline can have a significant impact on the friction between clothing and a giant rock. As the angle of incline increases, the force of gravity acting on the rock also increases, making it more difficult to move. This results in an increase in the amount of friction between the surfaces, making it even harder to move the rock.
