    Motion Negative
AI Thread Summary
The discussion revolves around the classification of velocity in relation to a motion sensor. When a person moves toward the sensor, their velocity can be considered positive, while moving away can be deemed negative. However, the designation of positive or negative velocity is subjective and depends on the chosen reference point. The key takeaway is that the distinction between the two velocities is what matters, not the labels themselves. Understanding this concept is crucial for analyzing motion in relation to a sensor.

Homework Statement


1 - A person moving toward the motion sensor with constant velocity..
2 - A person moving away from the motion sensor with constant velocity..


Homework Equations


For both statement above.. Is the velocity positive or negative?


The Attempt at a Solution



For the first statement .. i assume that the velocity is positive.. is it right?
For the second .. i assume that the velocity is negative .. is it right?

Really the choice is entirely up to you which one you want to call positive and which you want to call negative, the important part is that the two are different.
 

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...
