Multiple Choice: The frictional force and normal force are related how

[From: ] [author: ] [Date: 11-11-21] [Hit: ]
C.D.by half-They are directly related C.The reason is thatF = mu * Nwhere F is the friction force, mu is the coefficient of friction and N is the normal reaction.Unless you alter the surfaces then mu is a constant.......
A. inversely
B. they are not
C.directly
D.by half

They are directly related C.

The reason is that F = mu * N where F is the friction force, mu is the coefficient of friction and N is the normal reaction.
Unless you alter the surfaces then mu is a constant.

So we get F is proportional to N ( direct) and doubling N doubles F
