1

What is an electric field, general description?

This field is a conceptual quantity exists in all space

2

What is the electric field(E)?

The E field at a point in space is the force acting on a unit positive charge placed at that point. 

3

The equation for E field strength on a test charge at a point in space?

E = F / Q (V/m)

4

How can a force acting on a charge be calculated?

The force acting on a charge can be calculated from the E in which it is placed.

F = EQ

5

The E field of a positive point charge?

6

Superposition of electric fields(like charges)?

7

Electric field structure (like Charges)

8

Superposition of electric fields(unlike charges)

9

How can the acceleration of a charged particle be calculated? 

F = ma & F = Eq

a = qE/m

SUVAT can then be used to solve problems

V = u + at
