**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.

In the **first law, an object will not change its motion unless** a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Formally stated, Newton’s third law is: **For every action, there is an equal and opposite reaction**. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Newton’s second law of motion is **F = ma**, or force is equal to mass times acceleration.

Newton’s third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. … We sometimes refer to this law loosely as **action-reaction**, where the force exerted is the action and the force experienced as a consequence is the reaction.

Sir Isaac Newton worked in many areas of mathematics and physics. He developed the theories of gravitation in 1666 when he was only 23 years old. In 1686, he presented his **three laws** of motion in the “Principia Mathematica Philosophiae Naturalis.” By developing his three laws of motion, Newton revolutionized science.

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.

For every action **(force) there is a reactive force and the action and reaction forces are**. **equal in magnitude and opposite in direction**, and act upon different bodies. Often action/reaction occurs through contact forces. eg. two boats “pushing off” from each other.

Newton’s first law of motion states that **a body at rest will remain at rest position only** and a body which is in motion continues to be in motion unless otherwise they are acted upon by an external force. … When an object is in motion the velocity will not be equal to zero but the acceleration will be equal to zero.

The third law of motion states that **when one object exerts a force on another object, the second object instantaneously exerts a force back on the first object**. These two forces are always equal in magnitude but opposite in direction. These forces act on different objects and never on the same object.

In **the first law, an object will not change its motion unless** a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

**An object will not change its motion unless a force acts on it**. An object that is not moving remains at rest until something pushes or pull it.

The universe you live in right now, the planet that is revolving around a star and which you are a resident of, and all the processes that happen in this planet are said to be a result of four fundamental laws of nature: **Gravitation, Electromagnetism, Strong Interactions, and Weak Interactions**.

Newton gave **three laws** of motion that describe the motion of bodies. These laws are known as Newton’s Laws of motion. They describe the relationship between the forces acting on a body and its motion due to those forces.

These laws tell us exactly how things move or sit still, like why you don’t float out of bed or fall through the floor of your house. Newton’s **laws control how cars work, how water flows, how buildings** don’t fall down, and basically how everything around us moves.

Newton’s third law of motion states **that for every action, there is an equal and opposite reaction**. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. … State any two illustrations for Newtons third law of motion.

Newton’s Second Law of Motion It states that **the rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts**.

This is **a law** because it describes the force but makes not attempt to explain how the force works. A theory is an explanation of a natural phenomenon. Einstein’s General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.
