Page 1: Mechanics and Electrostatics
This page covers fundamental physics concepts including work, power, energy, and electrostatics. The content begins with mechanical principles and transitions to electrical forces and fields.
Definition: Work is defined as force multiplied by displacement W=F⋅d, measured in Joules.
Vocabulary: Mechanical efficiency is calculated as Total Mechanical Energy output divided by input, expressed as a percentage.
Example: In electrostatics, charging by induction occurs without contact, where electrons move away from negative charges toward positive charges.
Highlight: For momentum calculations, direction is determined by velocity, and conservation of momentum applies in all collisions.
Quote: "When friction does work, KE decreases."
The page includes detailed formulas for kinetic energy KE=½mv2, gravitational potential energy PE=mgh, and elastic potential energy PE=½kx2. Circuit analysis includes both series and parallel configurations, with specific rules for current and voltage relationships.
