|
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.(physicsclassroom.com)

|
states that the acceleration of an object is dependent upon two variables-the net force acting upon the object and the mass of the object.(physicsclassroom.com)

Detailed explanation-1: -Newton’s first law states that an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force. According to Newton’s first law, an unbalanced force is needed to move the book on your desk. You could supply the force by pushing the book.
Detailed explanation-2: -Newton’s First Law: Inertia Newton’s 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.
Detailed explanation-3: -Newton’s first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
Detailed explanation-4: -Newton’s first law of motion describes how an object moves when the net force acting on it is zero. According to Newton’s first law of motion, if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed.
