Practical work “FORCE”
1) What’s the definition of forcé?
What unit of force measured in?
2) What`s newton`s law of motion?
3) Find and write newton`s biography
4) Relate theseconcepts= distance/ speed/ velocity. Which equation connect then
5) Define mass/ gravity.
6) What unit is weight measured in?
7) How do you convert weight into mass?
8) What`s theacceleration?
9) Do heavier objets fall faster light ones? Explain

1)force is a physical quantity that measures the intensity of the exchange of momentum between two particles or particle systems
It ismeasured in Newtons (N)
2)Newton's Laws, also known as Newton's laws of motion are based on three principles which explain most of the problems posed by the dynamics, particularly those relating tothe motion of bodies

3) Sir Isaac Newton PRS MP (25 December 1642 – 20 March 1727 [NS: 4 January 1643 – 31 March 1727]) was an English physicist, mathematician, astronomer, naturalphilosopher, alchemist, and theologian, who has been "considered by many to be the greatest and most influentialscientist who ever lived." His monograph Philosophiæ Naturalis Principia Mathematica, published in 1687,lays the foundations for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of thephysical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler'slaws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution.
The Principia is generally considered to be one of themost important scientific books ever written, due, independently, to the specific physical laws the work successfully described, and for the style of the work, which assisted in setting standards...
