The acceleration of an object moving in a straight line can be determined from:
The area between the velocity-time graph and time axis
The slope of the velocity-time graph.
The area between the distance-time graph and time axis.
The slope of the distance-time graph.
Slope of velocity-time graph = BC / AC = v 2 - v1/ t2 - t1 = Acceleration
For uniform motion :
(a) the distance-graph is a straight line parallel to the time axis.
(b) the speed-time graph is a straight line inclined to the time axis.
(c) the speed-time graph is a straight line parallel to the time axis.
(d) the acceleration-time graph is a straight line parallel to the time axis.
What can you say about the motion of an object whose distance time-graph is a straight line parallel to the time axis ?
