The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. 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.

## What are Newton's first 3 laws?

The Newton's three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion. A body at rest persists in its state of rest, and a body in motion remains in constant motion along a straight line unless acted upon by an external force.

## What does Newton's 2nd law state?

Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

## What Newton's laws explain?

Answer: Newton's first law of motion explains how inertia affects moving and nonmoving objects. 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.

## What is the state of motion?

The state of motion of an object is defined by its velocity - the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity.

## Why do we call Newton's first law as law of inertia explain?

It is called the law of inertia because it tells that every material body has a property by virtue of which it resists the change in its state of rest or in its state of motion.

## How do you demonstrate Newton's first law?

Newton's first law states than an object at rest, assuming no force acts on it, will try to stay at rest. Demonstrate this by placing an index card on top of the plastic cup. After placing the penny on top of the index card, quickly remove the index card horizontally.
