Understanding Final Velocity: A Beginner's Guide

AI Thread Summary
Final velocity refers to the magnitude and direction of an object's speed at the end of a process. It is often associated with terminal velocity, which occurs when an object experiences decreasing acceleration until it reaches zero. At this point, the object's speed stabilizes, indicating that it has reached terminal velocity. The discussion also touches on the concept of final velocity in the context of collisions. Understanding these principles is essential for comprehending motion dynamics.

What is Final Velocity? :confused:
 
Physics news on Phys.org
In what context did you come across that expression?
 
the magnitude and direction of speed at the end of process
 
If you are talking about "terminal velocity", this term is sometimes (or always?) when objects go through restrained acceleartion. That is, the object's acceleration is not constant and is constantly decreasing until it reaches zero. The velocity when the acceleration is zero, is the terminal velocity.
 
Could also be talking about collision or something else, though.
 
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...
