Based on his storied research and teaching, Eric Mazur’s Principles & Practice of Physics builds an understanding of physics that is both thorough and accessible. Unique organization and pedagogy allow students to develop a true conceptual understanding of physics alongside the quantitative skills needed in the course.
1. Electric Potential Energy. When a charged particle moves in an electric field, the field exerts a force that can do work on the particle. The work can be expressed in terms of electric potential energy. Electric potential energy depends only on the position of the charged particle in the electric field.
28 lis 2019 · This paper provides a brief review of physics education research as a means for providing a context towards future work in promoting deep learning and fostering abilities in high-end reasoning.
In uniform E-field only: \[V_{AB} = Ed\] \[E = \dfrac{V_{AB}}{d}\] where d is the distance from A to B, or the distance between the plates in Figure \(\PageIndex{3}\). Note that this equation implies that the units for electric field are volts per meter.
The derivation for E = V/d is based on the definition of electric field as the force per unit charge. The equation states that the electric field (E) between two parallel plates of a capacitor is equal to the potential difference (V) between the plates divided by the distance (d) between them.
Voltage overview. The voltage at a point in empty space is a number (not a vector) measured in units called volts (V) . Near a positive charge, the voltage is high. Far from a positive charge, the voltage is low. Voltage is a kind of "electrical height". Voltage is to charge like height is to mass.
