An object can only gain speed if there is a net force on it. If a net horizontal force acting on an object is large enough, or acts for a long enough time, the object can aquire a speed up to just under the speed of light, 3 x 10^8 m/s.
The object is going at a constant speed, the value of which is given on the speed axis.
You cannot. A distance vs time graph only measures radial distance - that is, distance from the origin to the object. If the object is going around the origin along a circular path, the distance vs time graph will not show any change in distance.The [incorrect] answer that you are required to give is that the graph will be a horizontal line during that period. But as explained above, the horizontal graph only means the object has no movement towards or away from the origin, not that it has no movement.
Not necessarily. If the horizontal line is laying on top of the x-axis, then the speed is zero at any time, and the object isn't moving. But if the horizontal line is parallel to the x-axis, then the object is moving with constant speed.
No, but the slope of the graph does.
The distance versus time graph shows the position of the object. The slope of the line shows the velocity of the object. The velocity is the direction and speed of an object. If your slope has a positive slant that means you are going in a positive direction. If the slope has a negative slant your object is going in a negative direction. If your slope is zero (a horizontal line) that means your object has stopped and is about to change directions. In case you didnt know a positive slant looks like this on a graph.... / a negative slant looks like this on a graph.... \ postive is like sloping up a hill negative is like falling down the hill
It depends what you're measuring- If it's the speed you're measuring, the time goes on the horizontal axis (X-axis). If, however, you're measuring how long it takes for the object to get to a set speed- and it's the time you're measuring, time goes horizontally.
If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.
That the object is moving at a constant speed
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.
that would indicate that the object is at rest (static object) :D

The independent variable, in this case time, is on the horizontal axis of a speed graph.
If the line formed by the graph is straight, the speed is constant. A horizontal line would show the object as stationary.
time, distance
Not necessarily. If the horizontal line is laying on top of the x-axis, then the speed is zero at any time, and the object isn't moving. But if the horizontal line is parallel to the x-axis, then the object is moving with constant speed.
Distance-time graph will show a straight line with a positive slope. Speed-time graph will show a horizontal line at the uniform speed. Acceleration-time graph will show a horizontal line at a = 0.
You can use the steepness, or slope, of a line in a distance-time graph to determine the speed of an object if speed is constant. The slope of the line is calculated by dividing the change in distance by the change in time for that time interval.
It means that the object in question is moving at a constant speed.If the graph is a straight horizontal line, then the speed is zero.
