Answer:
The answer is A) relative motion.
Explanation:
As the name suggests, relative motion refers to the perceived velocity of a point in relation to another.
Some more instances would be the perceived velocity of a car if you're standing the next to the road (the car moves fast), if you're driving a car and moving at the same speed (the other car appears static) or if you're driving the opposite direction (the other car appars to move at double the speed).
It's important to notice that relative motion can be positve or negative.
Yes because you cannot establish credibility without a source that is experienced on the research topic. it would be like a janitor writing journals about brain surgery when he never went to school to get his doctorate degree and has no valid knowledge of the topic.
