Question

1. 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).

please make sure it's correct 100%

Answer 1

Explanation

According to newton first law of motion

Every body continues in its state of rest or uniform motion in a straight line unless it is compelled by some external force to change that state.

It says that if a body is at rest continues in its state of rest, external force has to applied to move it. For example, a chair lying on floor will continue to there unless we move it(apply external force).

Also, A body in uniform motion continues in its uniform motion in a straight line unless an external effort (force) is applied to it. It doesn't change its direction by itself. For example, when a vehicle moves, the mud sticking to its wheel flies off tangentially, moves in a straight line.

Also from newton second law of motion,

The rate of change of momentum of a body is directly proportional to the external force applied on the body and the change takes place in the direction of applied force.

In other words, force is directly proportional to both mass and acceleration. If F=0, and m can not be equal to zero, then a=0, results that rate of change velocity is zero.

It means velocity is either constant or zero.

If v is constant then uniform motion.

Thus, object has no interaction with the surrounding.
