The average speed of an object during a specified period of time is a. Always equal to the magnitude of the average velocity for the same period of time. b. Never equal to the magnitude of the average velocity for the same period of time. c.

Answer:

c. Equal to the magnitude of the average velocity for the same time period if the direction of motion does not change.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex]

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

The average speed of an object during a specified period of time is equal to the magnitude of the average velocity traveled or covered in the same time period and in a straight line i.e if the direction of motion does not change.
