The point on the graph will be higher (in the normal configuration of such graphs).
x and y
The slope of the speed/time graph is the magnitude (size) of the object's acceleration.
The slope of a speed vs time graph indicates an objects acceleration.
the answer is no; the speed of light is the universal speed limit, nothing travels faster
It goes faster
it means that the object is gradually getting faster
They don't. All objects fall at the same rate of speed because of weight.
The slope of a line on a distance-time graph represents the speed or velocity. The steeper the line is and the greater the slope of the line is, the faster the object is moving.
The mass and the trajectory of the object affect the speed at which the object will roll.
You can conclude that the acceleration of the object is not constant.
You're looking at one specific velocity/time graph that we can't see. From your description, we can tell that the object whose motion is described by that graph is moving at a constant rate of speed ... which is exactly what you just said while looking at the graph.
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
