Sir Isaac Newton

  Newton was born in 25 December of 1642 in England. Newton was an physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian, who has been " considered by many to be the greatest and most influential scientist who ever lived. He died in 20 March of 1727, in age 84.
  One of Newton's laws was the law of motion. The law has three parts, but I'l just explain the third law. According to Newton's third law, " for every action there is an equal and opposite re-action". What does this means? This means that for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.

                                         Let's study how a rocket works to understand Newton's third law 


                                           

                         The rockets action is to push down on the ground with the force of it's powerful
                    engines, and the reaction is that the ground pushes the rocket upwards with an equal force.
