 # Describe Newton's laws of motion?

Isaac Newton was the greatest scientist that had ever lived. The illustrious natural philosopher was born at Woolsthorpe Manor in Lincolnshire. He was one of the greatest thinkers of modern times.

In 1666, the fall of an apple led to his greatest discovery of all – the law of gravitation. He was knighted in 1705. His new ideas had given the great concepts and laws regarding motion and gravitation. His laws of motion could show the clear picture of motion of an object when force is applied on the body. Further the concept of gravitation and universal law of gravitation had given the new dimensions to physics.

The queries like why the things fall downwards? and how the universal objects are capable of moving without any forces being applied, have been answered after the development of the concept of gravitation. Thus, it is called Isaac Newton Gravity theory which is a worldwide well known theory which answered so many queries and helped a lot in the many scientific calculations.

## Newton’s Laws of Motion

The three laws of motion help us understand how objects behave when they are standing still, when moving and when forces act upon them.

• Newton’s 1st law – States that a body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it.
• Newton’s 2nd law – Sates that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
• Newton’s 3rd law – States that for every action there is an equal and opposite reaction. (5) (2)
