Study Notes
Confucius and His Philosophy
- Renowned philosopher known as the "Master" or "Great Sage."
- "Analects" is a collection of Confucius' teachings, compiled by his disciples after his death.
- Central concepts include Jen (Benevolence), Yi (Propriety), and Li (Ritual).
Paraphrasing
- Paraphrasing involves restating someone else's ideas in your own words.
- It is a legitimate way to present information when accompanied by proper citation.
- Different from summarization, as it provides a more thorough restatement.
Plagiarism
- Defined as the act of using someone else's work without proper attribution.
- Considered a serious academic offense and a form of intellectual theft.
- The term originates from the Latin word meaning "kidnapper."
Paraphrasing Techniques
- Vocabulary: Use synonyms to replace words in the original text.
- Word Form: Change the grammatical form of certain words to create a new meaning.
- Sentence Structure: Alter the arrangement of words while retaining the original meaning.
Force
- Interaction between two objects that alters their motion.
- Can cause movement, speed change, deceleration, or directional shift.
- Measured using a spring scale; unit of force is the Newton (N), defined as 1 kg accelerating at 1 m/s².
Newton's Laws of Motion
-
First Law (Inertia): An object remains at rest or in uniform motion unless acted upon by an unbalanced force.
-
Example: When a bus stops suddenly, passengers lurch forward due to inertia.
-
Second Law (Acceleration): Expressed as F = ma; the net force on an object is equal to its mass times its acceleration.
-
Acceleration increases with greater force and requires more force for heavier masses.
-
Formulas:
- ( a = \frac{F_{net}}{mass} )
- ( F_{net} = mass \times acceleration )
-
Third Law (Interaction): States that for every action, there is an equal and opposite reaction.
-
Examples include fish using fins and rocket propulsion.
Work and Power
- Work: The energy transfer when a force moves an object. Calculated as ( W = F \times d ).
- Unit of work is Joule (J), equal to Newton-meter (N·m).
- Power: Rate at which work is done; calculated by ( P = \frac{W}{t} ).
- Units of power include watt (W), kilowatt (kW), and horsepower (hp).
Energy
- Defined as the capacity to do work, measured in joules (J).
- Mechanical energy can exist as potential or kinetic energy.
Potential Energy
- Stored energy due to an object's position or state.
- Gravitational potential energy is calculated using ( PE = mgh ) (mass × gravity × height).
Kinetic Energy
- Energy of an object in motion, dependent on mass and velocity.
- Calculated using ( KE = \frac{1}{2} mv^2 ).
