    Control Variable
AI Thread Summary
To achieve constant velocity in a friction investigation, using a 60Hz motor to spin a threaded rod with a nut attached to the object is suggested. This setup provides a constant linear velocity through the motor's consistent angular speed. While it does not create constant acceleration, it maintains a constant force that counters the frictional force in the experiment. The method is appreciated for its effectiveness in meeting the experiment's requirements. This approach is timely and helpful for completing the lab assignment.

Hello, I am making a lab investigating friction of an object and I just need a "method" of controlling acceleration in the experiment so the object travels at a constant velocity. This is really the only way I can think of having the experiment work out correctly so I really need help with this. Any help is greatly appreciated, thank you!

How about a 60Hz motor spinning a threaded rod, with the nut attached to your object? The constant angular velocity of the motor will give you a constant linear velocity at the traveling nut. It's not a constant acceleration, but a constant force, which is opposed by a frictional force in your experiment, I would guess...
 
Thank you, greatly appreciated. This is due tomorrow you just helped me out a great deal. thanks
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging 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...
