time (s)- Q. 1. What does the shape of the graph suggest about the type of motion ? (A) The graph indicates non-uniform motion. (B) The graph indicates circular motion. (C) The graph indicates uniform motion. (D) The graph indicates uniform circular motion.
Answers
Answer:
The correct answer is option (A) The graph indicates non-uniform motion.
Explanation:
The shape of the graph suggests non-uniform motion. When an object is moving non-uniformly, it travels variable lengths over time intervals, which indicates varying speed. When examining a graph, it is clear that an object is not travelling at a constant speed if the plotted dots are not evenly spaced apart or if the distance travelled during each interval of time varies.
As, According to the graph we have seen that the graph first increase from O to A and B and C. After C it drops to D and after D it again started increasing to the E. So, this shows that the graph is non-uniform in nature.
In the case of uniform motion, the graph would show a straight line with equal intervals between the points, indicating constant speed. In uniform circular motion, the graph would show a sinusoidal pattern, indicating that the object is moving in a circle at a constant speed.
