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.
The x-t graph can't tell you anything about direction, so you can only make observations regarding speed, not velocity. For constant speed, the x-t graph is a straight line. The slope of the line is numerically equal to the constant speed.
A straight line.
The straight horizontal line on the graph says: "Whatever time you look at, the speed is always the same". This is the graph of an object moving with 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.
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
At constant speed, the distance/time graph is a straight line, whose slope is equal to the speed.
The x-t graph can't tell you anything about direction, so you can only make observations regarding speed, not velocity. For constant speed, the x-t graph is a straight line. The slope of the line is numerically equal to the constant speed.
A straight line.
anything.... since speed and/or direction are changing (and not necessarily at a constant rate), the graph can look like pretty much anything
The straight horizontal line on the graph says: "Whatever time you look at, the speed is always the same". This is the graph of an object moving with constant speed.
Not curved.
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.
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.
A straight line, through the origin, sloping up from left to right. The gradient of the graph will be the constant of proportionality.
The answer depends on whether it is a distance-time graph, speed-time graph or something else.
you do not all you do is look and
If a graph shows distance on the vertical axis and time on the horizontal axis, and the speed is steadily increasing, the line representing speed will be a straight line.
