WebHint: there may be more than one correct answer. Ms is dimensionless. us has the same dimensions as force. Ms can not be negative. Us can be negative. Us can not be greater than 1. Ms can be greater than 1. all objects have a unique us. Ms is only defined between two Show transcribed image text Expert Answer WebOct 13, 2024 · It is 0.04 (both μs and μk ) Static friction and Kinetic friction – explanation with the molecular cohesion theory When an object is static then due to molecular-level cohesion between its surface and the other surface on which it is resting, we need to apply a force to move it.

WebNov 11, 2024 · Answer: a) Fmax= μs.m.g b) Ff=(μs.m.g /2 c) a= (μs.m.g - μk.m.g) / m. Explanation: a) The friction force, is one of the components of the contact force, and can adopt any value to counteract an applied force, so the object doesn't move, till a maximum value, beyond which, if he applied force is larger, the object will start to move. WebCould μk or μs ever be greater than 1? Explain why or why not. Is the coefficient of friction the same as when the block was standing on its larger (or smaller) end? Is one value … painting plastic mirror frame
Why coefficient of kinetic friction is less than coefficient of static ...
WebSep 12, 2024 · Thus, the greater the angle of the incline, the greater the linear acceleration, as would be expected. The angular acceleration, however, is linearly proportional to sin θ and inversely proportional to the radius of the cylinder. Thus, the larger the radius, the smaller the angular acceleration.
