Which condition is described as an inverse gradient during braking?

• A. A normal gradient
• B. An inverse gradient
• C. A false gradient
• D. A peak gradient

Answer: (B)

During braking, speed decreases, so the rate of change of speed (the gradient on a speed-vs-time graph) is negative. That negative slope is the inverse of the positive slope you’d see when accelerating. So the condition described as an inverse gradient captures this reversal in direction of the gradient during braking. The other terms don’t fit because they don’t describe this sign-reversal behavior of deceleration.
