Any curved line on a distance/time graph indicates the presence of acceleration
that's causing a change in the magnituide of the velocity. But if the object's speed
is constant, and the acceleration is changing its direction only, then the line on the
D-T graph would remain straight.
In summary:
Every curved line on a D-T graph reveals acceleration, but not every acceleration
produces a curved line on a D-T graph.
No. It always indicates that the object is not accelerating.
No. It always indicates that the object is not accelerating.
its false
False. It has negative acceleration.
The slope of a speed vs time graph indicates an objects acceleration.
It means the object is decelerating - slowing down rather than speeding up. You can think of it as negative acceleration.
The graph is pretty nearly useless. A line (or segment) which is going up from left to right) indicates accelerating motion over that period, a horizontal line (segment) indicates motion at a constant speed and a line segment going downwards from left to right indicates retardation. However, there is no way to tell how fast anything is moving.
Indirectly, yes. If the graph is a straight line there is no acceleration, if the graph is not linear there is acceleration.
Speed-Versus-Time Graph and Distance-Versus-Time graph are the two types of graphs that can be used to analyze the motion of an accelerating object.
