Potential Energy of a system of charges

Temperature coefficient of resistivity

Power Transmission Transmitting electrical power is done much more efficiently at higher voltages due to the desire to minimize (I2R) losses. Consider power transmission to a small community which is 100 mi from the power plant and which consumes power at a rate of 10 MW. In other words, the generating station needs to supply whatever power it ...

2 CHAPTER 6. LAGRANGIAN MECHANICS 6.2 Hamilton’s Principle The equations of motion of classical mechanics are embodied in a variational principle, called Hamilton’s principle. Hamilton’s principle states that the motion of a system is such that the action functional S q(t) = Zt2 t1 dtL(q,q,t˙ ) (6.2) is an extremum, i.e. δS = 0.

The initial kinetic energy of the system is the kinetic energy 2of the projectile T 0 0 = 1 2 mv (taking the reference height as zero). After the collision the kinetic ... we are dealing with rectilinear motion and therefore the velocity vector becomes a scalar quantity. In order to understand the collision process we consider five different ...

Electric Potential Work and Potential Energy

It is by definition a scalar quantity, not a vector like the electric field. The SI unit of electric potential is the Volt (V) which is 1 Joule/Coulomb. The units of the electric field, which are N/C, can also be written as V/m (discussed later). Changes in the electric potential similarly relate to changes in the potential energy: 0 U V q Δ Δ=
