1. Introduction to Physics
What is Physics?
The study of matter, energy, and the interactions between them.
Examples from real life (e.g., motion, forces, electricity).
Mechanics (forces, motion)
Energy
Waves (light, sound)
Electricity
Magnetism
Nuclear physics
Units of Measurement:
Standard units (SI units: meter, kilogram, second, ampere, etc.)
Conversions (e.g., cm to m, kg to g, etc.)
2. Forces and Motion
Objective: Introduce the concept of forces and how they affect motion.
Basic concepts of force:
Definition of force: A push or pull on an object.
Unit of force (Newton, N).
Types of forces: Contact (friction, tension) vs. non-contact (gravitational, electrostatic).
Newton’s Laws of Motion:
First Law: Inertia (an object will remain at rest or in uniform motion unless acted on by an external force).
Second Law: F = ma (Force equals mass times acceleration).
Third Law: Action and reaction (every action has an equal and opposite reaction).
Speed, Velocity, and Acceleration:
Definition of speed and velocity.
Calculating speed (speed = distance/time).
Acceleration and its equation (a = (v - u)/t).
Graphical Representation of Motion:
Distance-time graphs.
Velocity-time graphs and how to calculate acceleration and displacement from them.
