Is the Electric Field a Force or an Energy Concept?

AI Thread Summary
The discussion centers on the nature of the electric field, questioning whether it is a force or an energy concept. An electric field is defined as the force experienced per unit charge, expressed mathematically as E = F/q₀, where F is the electric force and q₀ is a test charge. It is clarified that while it is often called a "force field," the electric field itself is not a force but rather the effect produced by electric charges that exerts forces on other charged objects. The distinction lies in understanding that the electric field generates forces rather than being a force itself. This conceptual clarification is essential for grasping the role of electric fields in physics.

I'm trying to understand the concept of the Electric Field. Is it a force itself? Or its some abstract piece of energy that generates a force?

I don't really get how its different from a force. Isn't it referred to as a "force field"?

As far as I know, it's not exactly a force.
An E-field is defined as followed:
\vec E \equiv \mathop {\lim }\limits_{q_0 \to 0} \frac{{\vec F}}{{q_0 }}

Here is q_0 a test charge and \vec F the electric force.
Therefore, an E-field is a force per charge so in N/C.

Since I didn't really know how to explain you this further, here's a quote from the Wikipedia: "an electric field or E-field is an effect produced by an electric charge that exerts a force on charged objects in its vicinity.".

Hope that helps :smile:

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
