Which formulas are these apart of? (coefficient of friction)times(cos (theta) times (m)(g)?

Question

and also viscosity(diameter)^2(velocity in z direction)/diameter(y^2)

Answer 1

i think these apply to dynamics, while second applies to fluid dynamics in particular

although i dunt really get ur question, cud u be more clearer?

Answer 2

The first formula is the formula for force due to friction in either a moving body or a static body.  So I'd guess dynamics or statics.  I'm not sure what the second formula's all about

Answer 3

the first seems to calculate the amount of energy consumed when moving an object on an incline. the second seems to deal with the energy of fluid in a rigid tube.

high school physics, is all i can think of.
