Question

State the law of gravitational ?

Answer 1

Isaac Newton's law of universal gravitation is a physical law describing the gravitational attraction between bodies with mass. It is a part of classical mechanics and was first formulated in Newton's work Philosophiae Naturalis Principia Mathematica, first published on July 5, 1687. In modern language it states the following:

Every point mass attracts every other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses:

Answer 2

Gravitational what?

Answer 3

Newton stated his Law of Universal Gravitation as follows:

The force acting between any two bodies is proportional to the product of the masses of the bodies, and inversely proportional to the square of the distance between them.

Because this is a proportional expression, we have to introduce a constant into the equation we write. This constant is called G ant it is equal to:6.67300 × 10-11 m3 kg-1 s-2

The equation to enable you to calculate the gravitational fore of attraction between any two bodies is:

F = G*m1*m2 / r²

F is in Newtons

G = as above

m1 = mass of one body in kg

m2 = mass of second body in kg

r = distance between the two bodies, measured from their centres, in metres. do not forget to square thuis in the equation.

    

Answer 4

Gravitational Potential Energy? GPE= mass * gravity(9.8m/s^2) * height.

GPE = mgh
