INERTIA AITRENI

Inertia Newton's first law

Newton's first law of motion is often referred to as the law of inertia. Inertia is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. An object at rest stays at rest and an object in motion stays in motion at the same speed and in the same direction unless acted upon by an unbalanced force.
