AI Thread Summary
Factors affecting stopping and directional control in basketball shoes include the friction coefficient, which can be measured using motion sensors and weight adjustments. A drawing board is clarified as a tool for holding drawing paper, but its relevance to the discussion remains unclear. Measuring the coefficient of friction can be achieved by determining the angle at which a shoe begins to slip, with added weight potentially improving accuracy. The conversation emphasizes the importance of incorporating variables that maximize traction and friction in testing. Understanding the forces involved in stopping and changing direction, specifically static and dynamic friction, is crucial for evaluating shoe performance.

Homework Statement
"How does the angle of a drawing board affect the friction coefficients of a basketball shoe?"

Would my question still work even if I can't direcrly measure the coefficient? Or should I change the DV variable to velocity, for example--for graphical/raw data + easier to measure, then anaylze the graph/convert/calculate for the coefficients?

I got curious of my basketball shoe's friction coefficient and tried replicating it on the closesr thing i had to a wooden floor.
Relevant Equations
Fr = uN
- Change DV to velocity and measure it with motion sensor
- create separate table/graph of friction coefficient using velocities and other information

Welcome to PF.

I'm having trouble understanding what you have posted. What is a "drawing board" in the context of your post? And measuring the ## \mu_S ## of a baskeball shoe on wood should be pretty straightforward, no?

A drawing board is a wooden board, typically with clips at the top and a rubber band near the end, used to hold the paper you are drawing on down.

I'm also not sure on how to measure the coefficient itself to create a raw data table and graph for the ia...
I can "easily" measure the angle in which it start to fall, but i can't rlly direct measure the coefficient, just when it starts to and how far it might for the DV part of my raw data graph

I think that as long as you add weight to the shoe (I'm not sure how best to do that -- maybe with small rocks?), you should get a good number with the angle measurement where the shoe starts to slip.

okay, thank you!
 
BTW, in the link I posted there are some tips about how to maximize the friction/traction from BB shoes. Be sure to incorporate those variables into your tests.

Also, an important part of BB is being able to stop quickly and change direction. Does that involve ##F_s## or ##F_d## ?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
