Define each variable in the equation for the Universal Law of Gravitation

Explanation:

The universal Law of Gravitation was propounded by Sir Isaac Newton.

The law states that "the gravitational force of attraction between two masses is a directly proportional to the product of their masses and inversely proportional to the square of the is the distance between them".

  Mathematically;

               F    =  

Where:

    F is the gravitational force of attraction

    G is the universal gravitation constant

    m₁ is the mass of object 1

    m₂ is the mass of object 2

    r is the distance between them.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
