- A
- B
- C
- D
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Recall the definition of acceleration.
Acceleration is the rate of change of velocity with respect to time. Positive acceleration means velocity increases with time.
Step 2: Analyze the given graphs.
(A) shows position increasing linearly — constant velocity (zero acceleration).
(B) shows position constant — object at rest (zero velocity, zero acceleration).
(C) shows velocity increasing linearly with time — constant positive acceleration.
(D) shows velocity constant — no acceleration.
Step 3: Conclusion.
Hence, the correct graph representing positive acceleration is (C).
Acceleration is the rate of change of velocity with respect to time. Positive acceleration means velocity increases with time.
Step 2: Analyze the given graphs.
(A) shows position increasing linearly — constant velocity (zero acceleration).
(B) shows position constant — object at rest (zero velocity, zero acceleration).
(C) shows velocity increasing linearly with time — constant positive acceleration.
(D) shows velocity constant — no acceleration.
Step 3: Conclusion.
Hence, the correct graph representing positive acceleration is (C).
