Physics HELP distances, velocity formulas

AI Thread Summary
The discussion focuses on clarifying key physics formulas related to distance and velocity. Participants seek explanations for the units involved, such as meters per second squared (m/s²) for acceleration, seconds (s) for time, and meters (m) for distance. Specific equations of motion are highlighted, including average velocity, acceleration, and the relationship between distance, initial velocity, and time. The conversation emphasizes the importance of understanding how to apply these formulas correctly. Overall, the thread aims to provide clarity on fundamental physics concepts.

:cry: well i need couple equations explained to me. such as the distances formula, and the velocity which I'm currentlyusing i really didn't understand what goes where m/s^2?, s?, m? and so on :cry:

do you mean instantaneous position/velocity/acceleration equations or average?

Acceleration is in meters per second per second, m/s^2
Time is in seconds, s
Distance and Displacement are in meters, m
Speed and velocity are in meters per second, m/s

Are you looking at the equations of motion? Any of these ones:

v(average) = \frac{s}{t}

a=\frac{v-u}{t}

s=ut + \frac{1}{2} a t^2

v^2=u^2 + 2as

If any of those are the equations you're having trouble with, I can help you understand how to use them.

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...
