#### Question

Read each 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

#### Solution

True

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.
