Question

ratio of speed and velocity​

Answer 1

Answer:

The ratio of instantaneous velocity to instantaneous speed is not a number, but rather a unit vector. It is called 'direction of motion'. If we are talking about average velocities and speeds, then one could call the the numerical value of the inverse of this ratio 'path efficiency'

Answer 2

The ratio of the velocity to thespeed of a particle is a unit vector along the direction of its velocity.

Speed is directly proportional to distance when time is constant: v ∝ s (t constant)

.....

Speed is inversely proportional to time when distance is constant: v ∝ ⅟t (s constant)

Combining these two rules together gives the definition of speed in symbolic form.

v = st☞ This is not the final definition.

Don't like symbols? Well then, here's another way to define speed. Speed is the rate of change of distance with time.
