gravitational fields Flashcards
what is the newton’s law of gravitation
Every object in the universe attracts every other object which is directly proportional to the product of their mass and square of the distance between them
Gravitational field
A region of space where a mass is placed experience gravitational force . Isolated master gravitational field lines are always radical inward
gravitational field strength or intensity
the force per unit mass acting on a small mass placed at a point is called the gravitational field strength of that point ( called ‘g’)
gravitational potential
the gravitational potential at a point of in the gravitational field is the amount og work done in moving unit mass from the infinity to that point
