AI Thread Summary
A parabolic graph is formed when plotting distance against velocity under constant acceleration due to the mathematical relationship between these variables. The equations of motion, such as s = ut + 1/2at^2, illustrate how distance (s) is influenced by initial velocity (u), acceleration (a), and time (t). Even without time, the relationship can be analyzed through the shape of the graph, which indicates a power function. The data provided shows a consistent increase in distance with increasing velocity, supporting the parabolic trend. Understanding this relationship is crucial for grasping concepts of motion in physics.

Homework Statement


Why is a parabola formed when a graph of distance(y axis) vs. velocity(x axis) is plotted against each other? (constant acceleration)

Homework Equations


s=ut+1/2at^2 (guessing?)
v^2-u^2 = 2as (guessing?)

The Attempt at a Solution


I don't know if there is any relationship between veloctiy and distance without knowing the time. But my teacher told me that time was not needed to prove it was a power function...?

Hi.

I'd say you're thinking about the problem in the wrong way.

Try drawing up the parabolic graph of distance vs velocity, and then ask yourself what the graph's shape is suggesting.

I hope that's a good enough hint in the right direction.

I don't really understand...
my data is like below
distance(m)
1
1.3
1.5
1.69
vel(m/s)
1.1675
1.325
1.4275
1.51

How can I prove what kind of function is it??

The graph looks like this...

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...
