What is newton’s law of gravitation ?
The law of gravitation states that any object with a mass will attract another mass with a force which is directly proportional to the product of the two masses and inversely proportional to the square distance between them.
According to newton’s law what is the force directly proportional to ?
The product of the two masses ( Mm)
According to newtons law what is the force of attraction inversely proportional to ?
The square of the distance between them (1/r^2)
What is the equation to work out the force of attraction ?
F = G (Mm/r^2 )
What is gravitational field strength?
The gravitational field strength is the gravitational force exerted per unit mass on a point within the field
