Why is there no distinction needed between instantaneous speed and magnitude of instantaneous velocity?

Options

  1. ABecause speed is a scalar quantity, while velocity is a vector quantity.
  2. BBecause both instantaneous speed and magnitude of instantaneous velocity are always positive.
  3. CBecause instantaneous speed and magnitude of instantaneous velocity have the same units.
  4. DBecause they are equal by definition, as speed and magnitude of velocity measure the same physical quantity.

Correct answer

D. Because they are equal by definition, as speed and magnitude of velocity measure the same physical quantity.

Step-by-step solution

Correct Option is : (D) Because they are equal by definition, as speed and magnitude of velocity measure the same physical quantity.
