The straight horizontal line on a graph is referred to as the x-axis. The vertical line on a graph is the y-axis.
That the force that causes the acceleration is not constant.
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.
The line would indicate motion at a constant speed.
A straight line sloping upwards on a position-time graph indicates that the object is moving with a constant positive velocity. The slope of the line represents the velocity of the object.
constant speed
The given speed is constant for the given period
Constant speed ... zero acceleration.
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
A straight line on a distance - time graph represents a "constant velocity".
a graph that does not have a straight line
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.
