If the mass of on is tripled and the radius is quadrupled how does the force change? the gravitational force is (minus) the gradient of the gravitational potential energy U grav F grav=ââU grav. Work If the force on the object is in the direction the object moves, the work done is: Work If the direction of the force is opposite the direction the object moves, work is: Force is NOT Work If the force is perpendicular to the direction the object moves, the work done is ⦠this ppt is a full detail about chapter 10 gravitation for class 9th. square of the distance between the objects. In other words, weight is dependent upon the surroundings. g = G M / r2 1. attraction between objects due to their masses. Doesnât know what gravity is though. Its magnitude depends only on r and has no angular dependence .⢠The Gravitational force between two bodies is independent of the presence of other bodies.
