Question
What was concluded from the observation of the following experiment?
- Object continues to stay in motion
- Newton's first law of motion
- Law of inertia
- All of the above
The correct answer is: All of the above
The correct answer is All of the above because according to the law of inertia, also called Newton's first law, postulates that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at a constant speed unless it is acted upon by a force.
