Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows:
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
The first law of motion defines only the natural state of the motion of the body (i.e., when the net force is zero). It does not allow us to quantify the force and acceleration of a body. The acceleration is the rate of change in velocity; it is caused only by an external force acting on it.

Newton's First Law of Motion states that an object in motion tends to stay in motion unless an external force acts upon it. Similarly, if the object is at rest, it will remain unless an unbalanced force acts upon it. Newton's First Law of Motion is also known as the Law of Inertia. What Newton's First Law is saying is that objects behave predictabl...
Newton's Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate. The larger the object's mass, the greater the force will need to be to cause it to accelerate. This Law may be written as force = mass x acceleration or: F = m * a Another way to state the Second Law is to say it takes more force to mov...
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that pushing on an object causes that object to push back against you, the same amount but in the opposite direction. For example, when you are standing on the ground, you are pushing down on the Earth with the same magnitude of force it i...
Sir Isaac Newton introduced the three Newton's laws of motion in 1687 in his book entitled "Philosophiae Naturalis Principia Mathematica" (or simply "The Principia"). The same book also discussed the theory of gravity. This one volume described the main rules still used in classical mechanics today.
Aug 11, 2021 · According to Newton’s first law, there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This law is also known as the law of inertia. Friction is an external force that causes an object to slow down. Inertia is the tendency of an object to remain at rest or remain in motion.
This lecture introduces Newton’s Laws of Motion. The First Law on inertia states that every object will remain in a state of rest or uniform motion in a straight line unless acted upon by an external force. The Second Law (F = ma) relates the cause (the force F) to the acceleration.

Privacy Manager. Newton's Laws of motion describe the connection between the forces that act upon an object and the manner in which the object moves. An understanding of forces and their tendency to balance or not balance each other is crucial to understanding how the object will change or not change its state of motion.
