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.
