Need help with physics project involving force of friction of various surfaces.

AI Thread Summary
The project involves rolling a soccer ball across various surfaces like turf, grass, and concrete to measure the force of friction. To calculate the force of friction, the initial and final forces on the ball must be determined and subtracted. The coefficient of friction for each surface is essential for the calculations. Additionally, knowing the weight of the ball is necessary to apply the relevant formula. Clear guidance on conducting the experiment is needed for accurate results.

Hey I have to do a project in which I am going to roll a soccer ball across different surfaces such as turf, grass, concrete, etc... and calculate the force of friction of each of these surfaces. I believe that i need to find the Initial force of the ball, then the final and subtract to find the force of friction. The thing is i have no idea how to conduct the actual experiment.

u can find the force of friction on the three different surfaces by knowing the cofficient of friction of the three surfaces and finding the weight of the ball & apply the formula.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
