Question

What is the nature of acceleration when the slope of a v–t graph is negative and constant?

• A. Uniform acceleration
• B. Uniform retardation
• C. Non-uniform acceleration
• D. Non-uniform retardation

Answer 1

The correct option is B Uniform retardation

• When the slope of a v–t graph is negative and constant, the velocity decreases at a constant rate.
• That means, there is uniform retardation (or deceleration).
