Question

Consider an object in uniform motion. Does this object have no interactions with its surroundings? Explain and show your detailed work, using only words without any calculations or numbers. Use your own words. (Your answer should not be less than 4 lines)

Answer 1

If an object is in uniform motion then its velocity remains constant.since change in velocity is called acceleration ,so acceleration of object is zero

From Newton's second law of motion

F=ma we can say that net force acting on object is zero.

That is there is no net interactions of object with its surroundings. But individual interaction may be possible , but vector sum of all these individual interaction must balance each other so that net interaction of object with its surroundings must be zero.

Example:- when object is moving in crossed electric and magnetic field in veocity selector such tha its velocity v=E/B then net force acting on charge particle is zero that is charge particle is in uniform motion, but during motion it interact with electricfield(E) as well as magnetic field(B).

If you understand the example then it's ok.otherwise let me know in comment section.I will give you different example.
