Constant speed is shown on a graph using straight lines. The straight line indicates that there are no fluctuations with the speed.
-- If the position/time graph is a straight line, then the speed is constant, and the slope of the line is the average speed, as well as the instantaneous speed at any moment. -- If the position/time graph is not a straight line, then the average speed between two moments in time is the slope of a straight line drawn between those two points on the graph.
A straight line on a distance/time graph means that the speed is constant. In every unit of time the distance increases by the same amount.
If the distance/time graph is a straight line that makes a constant angel with the time axis, then the body's speed is constant, and is equal to the slope of the straight line (tangent of the constant angel).
straight line curve
You generally plot a graph of Voltage v/s Current (with voltage on Y axis and current on the X axis). The graph will not be a straight line.
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
a graph that does not have a straight line
A straight line on a distance - time graph represents a "constant velocity".
The straight horizontal line on a graph is referred to as the x-axis. The vertical line on a graph is the y-axis.
A straight line with a positive slope on a position-time graph is the graph of an object that's moving in a straight line with constant speed.
linear graph
In that case, the graph would be a straight line.In that case, the graph would be a straight line.In that case, the graph would be a straight line.In that case, the graph would be a straight line.
A Linear graph
Linear = Straight line! So, a graph of a linear relationship is a straight line.
