Physics
Figure shows the displacement-time graph for four bodies A, B, C and D. In each case state what information do you get about the acceleration (zero, positive or negative).
Answer
The following information is obtained from the given figures —
- A → Zero acceleration since slope (i.e., velocity) is constant.
- B → Zero acceleration since slope (i.e., velocity) is constant.
- C → Negative acceleration (or retardation) since slope is decreasing with time.
- D → positive acceleration since slope is increasing with time.
