Newton and his greatest discoveries?

 who is newton:

law related to newton

1. Law of gravitation.

1. Newton laws of motions.

1. force(NEWTON)

1.law of gravitaion

What is Newton?(SI unit)

newton is the first  man who came with the idea of gravity .It was an evening of 1665 when he was trying to solve the mystery why planets revolve around the sun.suddenly an apple fell from the tree and the idea of gravity flashed in his mind.he discovered not only the cause of falling apple but also find the the force that cause the planets to revolve around sun.He call this as force of gravitation.we discuse his contributions in next lessons .kindly subscribe to get latest articles or lessons.

the are many laws that newton proposed names of some are follow.

Newton is the unit of force in SI units.newton is named on the name of scientist newton.

1 Newton is that force which produce acceleration of one meter per second square in the body of one kg mass

First equation of motion

A body is move with velocity ‘v_i­­­­­­­­’ after time ‘t’ it velocity become ‘v_f’ so, the acceleration’a’ is produce

Mathematically

  acceleration = change in velocity

                                Time

     a = v_f - v_i

                   _t

      at = v_f - v_i

  v_{f =} v_i + at

What is differences between Mass and Weight?

Well, mass is a measurement of how much matter is in an object; weight is a measurement of how hard gravity is pulling on that object. Your mass is the same wherever you are--on Earth, on the moon, floating in space--because the amount of stuff you're made of doesn't change. But your weight depends on how much gravity is acting on you at the moment; you'd weigh less on the moon than on Earth, and in interstellar space you'd weigh almost nothing at
all.

But if you stay on Earth,gravity is always the same,so it really doesn't matter whether you talk about weight or mass.

But scientist still like to careful to be careful about distinguishing between the two.if you talk about the mass about the mass of an atom you're always talking about the same thing;if you talk about it's weight,what you mean depends on where the atom is.

                                                                                                                                                          

 

overview between mass and weight

Mass	Weight
Mass is the quantity of matter	Weight is force of attraction called gravitation
It is scalar quantity	It is vector quantity
It is remain constant every where	It is change with the change of  gravitation  force
It is denoted by m	It is denoted by w It’s value is w =mg
It’s SI unit is kg	It’s SI unit is N
