What is the newton's law of universal gravitation?

Answer 1

The attraction between any two objects in the universe is inversely proportional to their distance from one another and is determined by the product of their masses.

Two objects of mass #m_1# and #m_2# separated by a distance #r# will attract each other with a force #F# as described by this equation:

#F = G(m_1m_2)/r^2#

where the universal gravitational constant is denoted by G.

#6.673×10^(−11) N m^2/(kg)^2#

The electromagnetic force, the weak nuclear force, the strong nuclear force, and gravity are the four known forces. Gravity is the weakest of these forces.

Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Mathematically, it can be expressed as F = G * (m1 * m2) / r^2, where F is the gravitational force between the two objects, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
