How can we transfer a table of motion data into a line graph?
1 answer:
Answer:
A table of motion (for a moving object) usually is something like:
Time I Position:
0s 1m
1s 3m
2s 5m
etc...
Where time is the independent variable and position represents the position of the object at that given time.
We can think in these points as coordinate pairs, for example, we can wrote these 3 pairs as:
(0s, 1m)
(1s, 3m)
(2s, 5m)
Now that we have these points, we can go to a coordinate plane and find these points
(The time would be on the horizontal axis, and position in the vertical axis)
Once you found the points, to complete the graph you need to find a line that connects the points.
An example of this is shown below, where the points used are the ones above, and the line should be straight.

The net force on the center of the rope is C. 14 N West
Explanation:
We have two forces acting on the rope:
- The force applied by Jack, 82 N, towards East
- The force applied by Tony, 96 N, towards West
Taking East as positive direction, we can rewrite the two forces as
where the second force is negative since its direction is west.
The two forces act along the same line, so we can calculate their resultant by simply calculating their algebraic sum. Therefore:
And the negative sign tells us that the direction is West.
