Write and explain Newton’s first law of motion

Explanation

Gallieo law of inertia was basis of Newton.s laws of motion
Newton first law of motion : Every body continues to be its state of rest or uniform motion in a straight unless compelled by some external force act otherwise.
A body at rest or motion of body moving with acceleration . Hence Newton first law can be repressented as follows:
Force is a physical quantity which can bring body are rest into motion and which can change velocity of object
From Newton.s first magnitude of force can not be known . This is its limitation.
