Coulomb's law explains that there is an electric force between any two electric charges placed at a distance from each other. Whether this electric force is repulsive if the charges are the same or attractive if they are different, this force is directly proportional to the magnitude of the charges, meaning it increases as their magnitudes increase, and inversely proportional to the square of the distance between them, in what is called the inverse square law.

Newton's second law describes the relationship between the force acting on an object and the acceleration the object will experience after the application of that force. When a force acts on an object, it causes it to accelerate. This acceleration is directly proportional to the magnitude of the force and inversely proportional to the mass of the object. The greater the mass of an object, the less acceleration it will have.
