⚠️ Common Exam Traps & Conceptual Pitfalls
Students frequently misinterpret the slope of a position-time graph as acceleration or confuse the slope of a velocity-time graph with velocity. Remember that the slope of an $x-t$ graph represents velocity, while the slope of a $v-t$ graph represents acceleration.
Suggest a suitable physical situation for each of the following graphs (Fig 2.12):
Step-by-Step Verified Solution
**Answer:** (a) A ball thrown upward with initial speed and returning. (b) A body moving with constant negative acceleration. (c) A body moving with zero acceleration (constant velocity).
**Step-by-Step Explanation:**
The graphs show: (a) x-t graph with positive then negative slope (ball thrown up and falling). (b) v-t graph with constant negative slope (constant deceleration). (c) a-t graph with zero acceleration (constant velocity).
