Newton's first law of motion states that an object will continue in a state of rest or uniform motion in a straight line unless acted upon by an external force.
What is Newton's first law of motion?
Newton's first law of motion states that an object will continue in a state of rest or uniform motion in a straight line unless acted upon by an external force.
Newton's first law of motion is also known as law of inertia.
The inertia of every object is the reluctance of the object to start moving or stop moving once the object is in motion.
Inertia depends on mass of the object.
Thus, Newton's first law of motion is also known as law of inertia.
