How does newton's second law of motion can be used to calculate the acceleration of an object?

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
