Average Average velocity Velocity

AI Thread Summary

The discussion focuses on the calculation of average and instantaneous velocity, questioning whether instantaneous velocity can be derived from two points on a function. It suggests that dividing the sum of two instantaneous velocities by two could yield an average, though this may not accurately reflect instantaneous conditions. The relationship between initial and final velocities is highlighted, affirming that the average velocity can be calculated as the sum of these velocities divided by two. The conversation emphasizes the importance of understanding the differences between average and instantaneous measurements in physics. Accurate calculations are essential for precise analysis in motion studies.

Instead of finding the average velocity http://theoryx5.uwinnipeg.ca/physics/onedim/node3.html , could you also find the instantaneous velocity of two points of a function and divide by 2 (or something similar, it may not be instantaneous).

If you know the initial and final velocity then yes the average is the sum of the two velocities divided by two.

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'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
