The average speed of an object is determined by dividing the sum of its initial and final speeds by two only when the acceleration is

Answer Details

The statement is true only when the acceleration is uniform. Uniform acceleration means that the object is changing its velocity by an equal amount in the same direction during equal intervals of time. In this case, the average speed can be calculated by dividing the sum of initial and final velocity by 2. However, if the acceleration is not uniform, the average speed cannot be calculated using this formula. In that case, we need to use other formulas that take into account the non-uniform acceleration of the object.
