What is stated in the law of inertia?

The law of inertia states that it is the tendency of an object to resist a change in motion. That is, an object at rest will stay at rest, unless it is acted on by an external force. Take a twenty minute nap.

What is the formula for the law of inertia?

Law of Inertia states that an object will not change its state of motion unless acted on by an unbalanced force. Static friction restricts the motion on an object that would take place on a frictionless surface under an applied force. Formula of static friction= f s ≤ µ s N, where µ s = coefficient of static friction and N = normal force.

What does the law of inertia say about an object?

What Is the Law of Inertia? The law of inertia states that 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. The law of inertia is sometimes referred to as Newton’s first law of motion.
