Physics and Chemistry Basics Quiz

Study Notes

Physics

Force and Motion
- Newton's Laws of Motion:
  1. An object at rest stays at rest; an object in motion remains in motion unless acted upon by a force (Inertia).
  2. F = ma (Force equals mass times acceleration).
  3. For every action, there is an equal and opposite reaction.
- Types of Forces:
  - Gravitational, frictional, tension, normal, and applied forces.
Energy
- Forms of Energy: Kinetic, potential, thermal, chemical, electrical, nuclear.
- Law of Conservation of Energy: Energy cannot be created or destroyed, only transformed.

Chemistry

Atoms and Elements
- Structure of an Atom: Protons, neutrons, and electrons.
- Periodic Table: Organized by atomic number; groups and periods indicate similar properties.
Chemical Reactions
- Types of Reactions:
  - Synthesis, decomposition, single replacement, double replacement, combustion.
- Indicators of a Chemical Reaction: Color change, temperature change, gas production, formation of precipitate.

Biology

Cell Structure and Function
- Basic Unit of Life: The cell.
- Types of Cells:
  - Prokaryotic (no nucleus) and Eukaryotic (with nucleus).
- Cell Organelles:
  - Nucleus, mitochondria, ribosomes, endoplasmic reticulum, and cell membrane.
Photosynthesis and Respiration
- Photosynthesis: Process by which plants convert sunlight into chemical energy (glucose).
  - Equation: CO2 + H2O + light energy → C6H12O6 + O2.
- Cellular Respiration: Process of breaking down glucose for energy.
  - Equation: C6H12O6 + O2 → CO2 + H2O + ATP (energy).

Earth Science

The Earth and Solar System
- Structure of the Earth: Crust, mantle, outer core, inner core.
- Types of Rocks: Igneous, sedimentary, metamorphic.
- The Water Cycle: Evaporation, condensation, precipitation, and collection.
Weather and Climate
- Factors Affecting Weather: Temperature, humidity, precipitation, wind.
- Climate Zones: Tropical, dry, temperate, polar, continental.

General Scientific Skills

Scientific Method
- Steps: Observation, hypothesis, experimentation, data collection, conclusion.
- Importance of control and variables in experiments.
Data Interpretation
- Graphs: Bar, line, and pie charts for representing data.
- Understanding units of measurement: SI units (meters, kilograms, seconds).
