Question

Describe Newton's laws of motion?

Answer 1

Newton's laws of motion:

1. Isaac Newton was the most brilliant scientist that ever lived. Woolsthorpe Manor in Lincolnshire is where the great natural philosopher was born. He was one of the most influential philosophers of our time.
2. The fall of an apple in 1666 led to his most important discovery - the law of gravity. In 1705, he was knighted. His new notions and principles about motion and gravitation were based on his new thoughts.

Newton's first Law:

According to Newton's first law, a body at rest or in uniform motion will continue to be in that condition up to and until it is exposed to a net external force.

Newton's second Law:

According to Newton's second law, the force is given by the rate of change of momentum.
$$\begin{gathered} \mathrm{Force}=\mathrm{Mass}\times \mathrm{Acceleration} \\ F=\frac{dP}{dt} \end{gathered}$$

Where F is the force, P is the momentum and t is the time.

Newton's third Law:

According to Newton's third law, every action has an equal and opposite response.

Force acting from A to B is equal to the negative of force acting from B to A.
$F_{AB}=-F_{BA}$
