A time line not only shows the chronological order in which a set of events occurred, but also, if done to scale, gives a visualization of the relative time between events.

What is the meaning of each of the following features of a velocity-time graph the slope of the line?

The slope of a line on a velocity-time graph is acceleration.


Does the time change as you go north or south of the Equator along the same longitude line?

No, the time does not change as you move north or south along the same longitude line. Time zones are determined by lines of longitude, so as long as you stay on the same line, the time remains constant.


On a V-t graph how does constant acceleration appear?

On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative, the line slopes down to the right (speed decreases as time increases).


What best explains how a plot of concentration vs time for a reactant of a chemical reaction can be used to determine the instantaneous rate of a reaction at time equals 10 s?

1) Find time = 10 s on the curve. 2) Draw a line tangent to the point time = 10 s on the curve. 3) Use two points on the tangent line to find the slope of the line. 4) The slope of the line is the instantaneous rate in M/s.


What is the meaning of a steeper line on a distance v. time graph?

The slope will tell you how much change of Y to X >.
