Question

For a particle moving with constant acceleration in a straight line, the average speed and magnitude of average velocity are always equal.

• A. True
• B. False

Answer 1

The correct option is B False

Average speed:

• It is the total distance traveled by the object in a particular time interval
• It is a scalar quantity.

Average velocity:

• It is the change in position or displacement divided by the time intervals in which the displacement occurs.
• It is a vector quantity.

When a particle moving with constant acceleration:

• The particle can reverse the direction therefore, the average speed is not always equal to the magnitude of average velocity.

Hence, the given statement is false.
