I understand the equation to find the coefficient of friction.
fr = a/b
a -> height of the ramp
b -> length of the base of the ramp.
But i understand that it's also possible to find friction coefficient using angle of elevation of the ramp.
So if i know the angle of elevation and...
After a tedious amount of research, i seem to have stumbled across something called 'skin friction' which seems to support what i have explained.
Eg. "Skin friction drag is caused by the actual contact of the air particles against the surface of the aircraft. This is the same as the friction...
Are there any simple drag experiments (one with limited knowledge in physics and expensive equipment) can conduct?
Perhaps one with which involves varying materials.
Nono, I'm asking, if something have high friction on the sliding ramp, would it also mean that it has high friction in water?
Eg. sandpaper on the ramp would be high friction, but does that automatically mean the friction is quite high in water?
Hi, I'm new to this forum.
I'm currently doing a project on the coefficients of different materials used in sports so as to study the effects they have in their respective sports.
Because we lack the equipment and knowledge to calculate drag, i'd like to ask whether a material having high...
