A scientific theory is an elaborate and deep explanation of a natural phenomenon in nature.
The scientific theory is formed after the results and evidence from various experiments of a different hypothesis are combined due to which theory explains the depth of any phenomenon. The scientific theory is different from a scientific hypothesis as a hypothesis is a limited explanation based on results but a theory is based on the predictions of the experimental outcome.
The difference between the above velocities is that they exist in opposite direction of each other. or it can be said that they are negative vectors of each other.
