  • Functions: Relation between a set of inputs and outputs.
  • Equations: Mathematical statements asserting the equality of two expressions.
  • Probability: Measure of the likelihood of an event.

Physics

• Fundamental Concepts:

  • Force: Influence that causes an object to change its velocity.
  • Energy: Capacity to do work, exists in different forms (kinetic, potential).
  • Mass: Measure of the amount of matter in an object.

• Laws of Physics:

  • Newton’s Laws of Motion:
    1. An object in motion stays in motion unless acted on by a force.
    2. Force equals mass times acceleration (F = ma).
    3. For every action, there is an equal and opposite reaction.
  • Conservation Laws: Energy and momentum in isolated systems remain constant.

Chemistry

• Basic Concepts:

  • Atoms: Basic unit of matter composed of protons, neutrons, and electrons.
  • Molecules: Two or more atoms bonded together.
  • Chemical Reactions: Process in which substances interact to form new substances.

• Key Principles:

  • The Periodic Table: Arrangement of elements based on atomic number and properties.
  • Acids and Bases: Acids donate protons (H+), while bases accept protons.
  • Stoichiometry: Calculation of reactants and products in chemical reactions.

• Types of Bonds:

  • Ionic Bonds: Transfer of electrons between atoms.
  • Covalent Bonds: Sharing of electrons between atoms.
  • Metallic Bonds: Pooling of electrons among a lattice of metal atoms.

Branches of Mathematics

• Arithmetic involves basic operations such as addition, subtraction, multiplication, and division.
• Algebra uses symbols and rules to manipulate variables, solve equations, and express relationships between quantities.
• Geometry focuses on shapes, sizes, properties of space, and relationships between objects in space.
• Calculus deals with change and motion, using differentiation to find rates of change and integration to find areas and volumes.
• Statistics involves collecting, analyzing, interpreting, and presenting data to reveal insights and patterns.

Key Concepts in Mathematics

• Functions are relationships that assign a unique output value for each input value, commonly represented by equations or graphs.
• Equations are mathematical statements asserting the equality of two expressions, and solving them involves finding the value of unknown variables.
• Probability measures the likelihood of an event occurring, ranging from 0 (impossible) to 1 (certain).

Fundamental Concepts in Physics

• Force is an influence that causes an object to change its velocity, either in direction or speed.
• Energy is the capacity to do work, taking different forms like kinetic energy (due to motion) and potential energy (due to position).
• Mass is a measure of the amount of matter in an object, often expressed in units like kilograms.

Laws of Physics

• Newton's Laws of Motion describe the relationship between force, mass, and acceleration.
  • An object at rest stays at rest, and an object in motion stays in motion at constant velocity, unless acted upon by a net force.
  • Force is equal to mass times acceleration (F = ma).
  • For every action, there is an equal and opposite reaction.
• Conservation Laws state that certain quantities in isolated systems remain constant, such as the conservation of energy and the conservation of momentum.

Basic Concepts in Chemistry

• Atoms are the fundamental building blocks of matter, composed of protons, neutrons, and electrons.
• Molecules are formed when two or more atoms bond together, either through sharing or transferring electrons.
• Chemical Reactions involve the transformation of substances into new substances by breaking and forming chemical bonds.

Key Principles in Chemistry

• The Periodic Table organizes elements based on their atomic number and recurring chemical properties, providing insights into their reactivity and behavior.
• Acids donate protons (H+), increasing the concentration of hydrogen ions in solution, while bases accept protons, reducing the concentration of hydrogen ions.
• Stoichiometry involves calculating the amounts of reactants and products involved in chemical reactions using balanced chemical equations.

Types of Bonds

• Ionic Bonds occur when electrons are transferred between atoms, creating positively and negatively charged ions that attract each other.
• Covalent Bonds form when atoms share electrons to achieve a stable electron configuration, resulting in the formation of molecules.
• Metallic Bonds involve a pool of electrons shared among a lattice of metal atoms, resulting in high electrical and thermal conductivity.
