Answer: 6. His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
7. Inertia & Newton's First Law of Motion . Example - A body, such as a soccer ball, will remain at rest unless acted upon by an external force.
8. inertness, especially with regard to effort, motion, action, and the like; inactivity; sluggishness. Physics. the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force. an analogous property of a force: electric inertia.
9. First law gives the qualitative definition of force. Because force is needed to push,pull and bring objects into motion.hence newtons first law of motion gives a qualitative definition of force.
Answer:
1.first law states that when a body is in rest it doesn't move but it is in motion it will be in motion
