AI Thread Summary
The area under the lines on a velocity-time (VT) graph represents displacement, which can be calculated using the formula: displacement = velocity x time. To find the slope of the lines, which indicates acceleration, use the formula: acceleration = change in velocity / change in time. For straight line segments, divide the area into triangles and trapeziums for accurate calculations. To create corresponding acceleration and displacement graphs, plot the calculated values against time on a separate graph. Understanding these concepts is essential for accurately interpreting VT graphs.

hey everyone,
so i kno that the area underneath the lines represent displacement and that the slope of the lines on vt graphs represent acceleration but how do i go about measurign them and actually getting numbers answers? See the question i am trying to answer shows a vt graph and asks me to construct a a and d graph corresponding with it...help would be much appreciated thank you

well if the graph is just consists of straight lines then divide it into triangles and trapeziums and calculate the area.
as for finding the slope of the lines use this (y2 - y1) / (x2 - x1). it is the "rise" over "run".
 


Hi there,

To measure displacement on a VT graph, you can use the formula: displacement = velocity x time. This means that you can calculate the displacement by finding the area under the line on the graph. The units for displacement would be in meters (m) or any other unit of length, depending on the context of the problem.

To measure acceleration on a VT graph, you can use the formula: acceleration = change in velocity / change in time. This means that you can calculate the acceleration by finding the slope of the line on the graph. The units for acceleration would be in meters per second squared (m/s²) or any other unit of acceleration, depending on the context of the problem.

To construct an A (acceleration) and D (displacement) graph corresponding to the VT graph, you can plot the acceleration and displacement values on a separate graph with time as the x-axis. The acceleration values would be represented by the slope of the line at each point, and the displacement values would be represented by the area under the line at each point.

I hope this helps. Best of luck with your problem!
 
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...
