The force of gravity is an attractive force, whose magnitude is given by [tex]F=G\frac{m_1 m_2}{r^2}[/tex]
Explanation:
The force of gravity is one of the four fundamental forces of nature (the weakest one). It is an attractive force that is exerted between every object that has mass.
The magnitude of the gravitational force between two objects is given by the equation:
[tex]F=G\frac{m_1 m_2}{r^2}[/tex]
where :
[tex]G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}[/tex] is the gravitational constant
[tex]m_1, m_2[/tex] are the masses of the two objects
r is the separation between them objects
We notice from the equation that:
- The gravitational force is proportional to the product of the masses: so if the masses increase, the force will increase as well
- The gravitational force is inversely proportional to the square of the distance: so if the distance increases, the force will decrease
