Newton's first law of motion

Newton's first law of motion states that a body at rest will remain at rest and a body in motion will continue in motion in a straight line with uniform speed, unless it is compelled by an external force to change its state of rest or of uniform motion .

to justify this statement let's take an example . Suppose the book is lying on the table point it is at rest. The book will not move by itself , that is ,it cannot change its position of rest by itself . It can change its state of rest only when compared by the force of our hands, that is when we lift the book from the table .Thus comma the position of rest of the book has been changed by the external force of our hand. and this observation supports the first part of the first law of motion

Answer 2

Answer:

Newton's first law of motion states that a body at rest will remain at rest and a body in motion will continue in motion in a straight line with uniform speed, unless it is compelled by a external force to change its state of rest or of uniform motion
