Chapter 5 – Force and Motion I

Chapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.

Chapter 29 – Electromagnetic Induction

Faraday’s Law of Induction: - The induced emf in a closed loop equals the negative of the time rate of change of the magnetic flux through the loop. dt ε= − dΦB - Increasing flux ε< 0 ; Decreasing flux ε> 0 - Direction: curl fingers of right hand around A, if ε> 0 is in same direction of fingers (counter-clockwise), if ε< 0

Chapter 6 – Force and Motion II

A centripetal force accelerates a body by changing the direction of the body’s velocity without changing its speed. v, a = ctes, but direction changes during motion.-Centripetal force: a, F are directed toward the center of curvature of the particle’s path. 3 III. Non-Uniform circular motion

Combination of Waves

Interference of Waves When light waves travel different paths, and are then recombined, they interfere. Each wave has an electric field whose amplitude goes like: E(s,t) = E 0 sin(ks-ωt) î Here s measures the distance traveled along each wave’s path. Mirror 1 2 * + = Constructive interference results when light paths differ

Breakdown in Solid Dielectrics - BU

When solid dielectrics are subjected to high electric fields, failure occurs due to electrostatic compressive forces which can exceed the mechanical compressive strength. If the thickness of the specimen is d0 and is compressed to thickness d under an applied voltage V, then the electrically developed compressive stress is in equilibrium.

Section 4: Electrostatics of Dielectrics

This property of dielectrics is known as polarizability. Basically, polarizability is a consequence of the fact that molecules, which are the building blocks of all substances, are composed of both positive charges (nuclei) and negative charges (electrons). When an electric field
