We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. ]]> 2020-11-11 16:40:32 UTC https://padlet.com/bagheshri33802019/ywvm5qbve0q1e6gk/wish/913453331 Newton's universal law of gravitation bagheshri33802019 https://padlet.com/bagheshri33802019/ywvm5qbve0q1e6gk/wish/913487891 Everybody in the universe attracts every body with a force,which is directly proportional to the product of their masses and inversely proportional to the square of distance between them.The more massive the objects,the stronger the force of attraction is.
SI unit of G=Nm^/kg^.

F=ma       (a=g)
F=mg
F=GMm/d^
mg=GMm/d^
g=GM/D^
(R=radius of the earth)
g=GM/R^
  1. The value of g is more at the poles(9.9 m/s^)
  2. The value of g is less at the equator(9.8 m/s^)
  • If an object is projected vertically upward, a=-g=-9.8 m/s^,final velocity is zero,v=0.
  • If an object is let fall from a height, a=g=9.8 m/s^,intial velocity is zero,u=0.
