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

Answer

True.
Explanation:
A car moving on a straight highway with constant speed will have constant velocity. Since acceleration is defined as the rate of change of velocity, acceleration of the car is also zero.
