The numerical value of the ratio of average velocity to average speed is
Correct answer: D. equal to or less than one
- A. always less than one
- B. always equal to one
- C. always more than one
- D. equal to or less than one
Explanation
Average velocity considers both magnitude and direction, while average speed considers only magnitude. Therefore, the ratio of average velocity to average speed can be equal to one or less than one, depending on the direction of motion. If the motion is in a straight line, it equals one; otherwise, it's less than one.Incorrect Options Explanation:(a) always less than one: This is not necessarily true since the ratio could be one or less depending on the direction of motion.(b) always equal to one: This is not true as average velocity and average speed can differ when the motion is not in a straight line.(c) always more than one: This is incorrect; the ratio can be one or less, as explained earlier.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
