Per NCERT, the SLOPE of the velocity-time graph represents acceleration. What does a NEGATIVE slope mean?
ANo physical meaning
BThe object is at rest
CNegative acceleration (the object is decelerating if v > 0; or accelerating in the opposite direction)
DPositive acceleration
Answer & Solution
Correct answer: C. Negative acceleration (the object is decelerating if v > 0; or accelerating in the opposite direction)
Per NCERT §2.3, negative slope on v-t = negative acceleration. Effect depends on v sign.
