Chapter 24 – Capacitance and Dielectrics

- Capacitance is a measurement of the ability of capacitor to store energy (V = U / q). Capacitors in Vacuum - Parallel Plate Capacitor: uniform electric field between the plates, charge uniformly distributed over opposite surfaces A Q E εo εo σ = = d A V Q C ab = =ε0 A Qd V E d o ab ε 1 = ⋅ = ε0 = 8.85 x 10-12 F/m

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

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

7. Kinetic Energy and Work Kinetic Energy

Kinetic Energy: The kinetic energy of a moving object: k = 1 2 mv 2 • Kinetic energy is proportional to the square of the velocity. If the velocity of an object doubles, the kinetic energy increases by a factor of four. • Kinetic energy is proportional to the mass. If a bowling ball and a ping pong ball have the same velocity, the bowling ...

STEMonstrations - Kinetic and Potential Energy - NASA

Kinetic energy (KE) is a form of energy related to an object’s motion. KE could be translation (moving from one place to another), vibration, or rotation. KE is calculated using an object’s mass and velocity. Like PE, KE is also measured in Joules (J).
