The equation for this would be linear and therefore produce a straight line, however the line can have slope so : ------ or / or | or any straight line in any direction.
If the constant acceleration is positive, the graph would be an exponential (x2) graph. If there is constant acceleration, then velocity is always increasing, making the position change at an ever increasing rate.
At constant speed, the distance/time graph is a straight line, whose slope is equal to the speed.
I would like to state first that you misspelled horizontal. The answer to your question is Constant speed.
According to the ideal gas law, pressure times volume is constant. We'll call that constant c. PV=C, P=c/V, so pressure is inversely related to volume, so it would look like the graph y=1/x multiplied by a constant.
The graph is a straight line. Its slope is the speed.
No - a line graph may peak and trough depending on the data marked on the graph - a bit 'like join the dots'.
it is a wave like movement. due to the rhythmic movement of diagonal muscles the move wave like.
That kind of depends on what is being graphed. -- On a graph of acceleration vs time, the graph is a straight line that lays right on top of the x-axis, because the acceleration is a constant zero. -- On a graph of speed vs time, constant speed is a horizontal line, parallel to the x-axis. -- On a graph of distance vs time, constant speed is a straight line with a positive slope; that is, it rises as it progresses toward the right.
Constant velocity implies zero acceleration, so you would have a horizontal line, identical to the x-axis.
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
anything.... since speed and/or direction are changing (and not necessarily at a constant rate), the graph can look like pretty much anything
In a velocity-time graph it will be the time axis (where velocity = 0). On a distance-time graph it will be a line parallel to the time axis: distance = some constant (which may be 0).
