Answer:
a). The natural state of an earthly object is to be at rest.
Answer:
The correct option for this question is option b) a body is moving and no unbalanced force acts on it, it will continue to move at constant speed in a fixed direction.
Explanation:
Galileo Galilei was an Italian philosopher, astronomer, and mathematician who made important contributions to the study of astronomy, the mechanics of matter, and the development of numerous new scientific methods. A falling object should gain equal amounts of velocity at equal times, according to Galileo. This also suggests that it will fall as the speed rises steadily. However, there was a problem with proving this - Galileo was unable to observe the object's velocity in free fall, and technology at the time was unable to capture such high speeds. Galileo attempted to reduce the speed of the falling object by replacing it with a ball that was rolling down an incline. He reasoned that a ball rolling down a ramp would speed in the same way that a falling ball would since free-falling is fundamentally identical to a completely vertical ramp.
As a result, Galileo deduced from Newton's First Law of Motion that an object moves at a constant speed when there is no external force acting on it.
