Question

define newtons first law of motion and give its significance

Answer 1

The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. Newton's first law of motion is often stated as. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Answer 2

Answer:

Newton's first law of motion 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. This is normally taken as the definition of inertia.

Newton's first law has a great significance. for example, people inside the bus tend to move forward even if the bus come to rest after reaching certain velocity
