Thanks Simon, I have tried googling it and I didn't get quite the answer I was looking for.Simon Bridge said:Hint: is Newton's Gravity ever repulsive? What about the electrostatic force?
You can also just google "comparison coulomb Newton"

Newton's 3rd Law of motion is not the law of gravitation. The third law is the law of action and reaction. The law of gravitation is a different beast altogether.Brian S. said:What would be the easiest way to describe the similarities and differences between the two laws, other than the fact that their formulas are built similarly and they use different measurements. Any input would be great; I am currently having a brain block!
Coulombs Law:F=K (q1*q2)/r^2
Newtons 3rd Law: F=G(m1*m2)/r^2
Coulomb's law is a fundamental law of physics that describes the electrostatic interaction between charged particles. It states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Newton's law of gravitation, on the other hand, describes the gravitational interaction between two objects with mass. It states that the force of attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Coulomb's law is much stronger than Newton's law of gravitation. This is because the force between charged particles is much stronger than the force between objects with mass. For example, the electrical force between two electrons is about 1036 times stronger than the gravitational force between them.
No, these laws cannot be used interchangeably. They describe completely different physical phenomena and have different mathematical equations. While both laws involve an inverse square relationship, the constants and variables involved are different.
While Coulomb's law and Newton's law of gravitation describe different phenomena, they are both based on the concept of force acting between two objects. In fact, Coulomb's law can be seen as a special case of Newton's law of gravitation, where one of the masses is much smaller than the other.
Yes, there are many real-life examples where both laws are applicable. For example, the force of attraction between protons in an atomic nucleus is described by Coulomb's law, while the force of attraction between planets in our solar system is described by Newton's law of gravitation. Both laws are also used in engineering and technology, such as in the design of electrical circuits and the trajectories of spacecrafts.
