Question
Read statement below carefully and state with reasons and examples, if it is true or false;
A particle in one-dimensional motion.
With zero speed at an instant may have non-zero acceleration at that instant.
✓

Answer

True.
Explanation:
When an object is thrown vertically up in the air, its speed becomes zero at maximum height. However, it has acceleration equal to the acceleration due to gravity (g) that acts in the downward direction at that point.
