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.
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.
If time is along the horizontal axis, and speed up the vertical, then a horizontal line indicates that at all times the speed remains at a fixed value. Hence the object is travelling at a constant speed of v, where v is the height of the horizontal line.
The slope of a speed-time graph represents the acceleration of an object. A steeper positive slope indicates faster acceleration, while a negative slope indicates deceleration. A horizontal line indicates a constant speed with zero acceleration.
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.
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.
that would indicate that the object is at rest (static object) :D
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.
If an object is not moving, its speed-time graph would be a horizontal line at the zero speed level. This is because the speed of the object is constant at zero, indicating that it is not experiencing any motion or changes in speed over time.
A speed graph shows how an object's speed changes over time. The horizontal axis represents time, while the vertical axis represents speed. The slope of the line on the graph indicates the acceleration or deceleration of the object.
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.
