,1. Question: At rest means:
A. v(t) > 0
B. v(t) < 0
C. v(t)=0
D. a(t)>0
Correct Answer: C. v(t)=0
Rationale: A particle is at rest whenever its velocity equals zero at that moment.
Exam Tip: “At rest” = velocity is zero, not acceleration.
2. Question: A particle is moving to the right when:
A. v(t)<0
B. v(t)=0
C. v(t)>0
D. a(t)<0
Correct Answer: C. v(t)>0
Rationale: Positive velocity means motion in the positive direction.
Exam Tip: Right = positive velocity.
3. Question: A particle is moving to the left when:
A. v(t)>0
B. v(t)<0
C. a(t)>0
D. x(t)=0
Correct Answer: B. v(t)<0
Rationale: Negative velocity means motion left.
Exam Tip: Left = negative velocity.
, 4. Question: Speed is decreasing when:
A. a(t) & v(t) have opposite signs
B. a(t) & v(t) have same signs
C. v(t)=0
D. x(t)=0
Correct Answer: A. a(t) & v(t) have opposite signs
Rationale: Opposite signs mean acceleration is working against motion.
Exam Tip: Opposite = slowing down.
5. Question: Speed is increasing when:
A. a(t)=0
B. a(t) & v(t) have same signs
C. x(t)=0
D. v(t)=0
Correct Answer: B. a(t) & v(t) have same signs
Rationale: Same direction means speeding up.
Exam Tip: Same sign = faster.
6. Question: Speed equals:
A. v(t)
B. a(t)
C. |v(t)|
D. x(t)
Correct Answer: C. |v(t)|
Rationale: Speed is the absolute value of velocity.
Exam Tip: Speed is never negative.
