Fundamental Concepts
- Space: Three-dimensional expanse that makes up our universe.
- Time: Measure of the duration between events.
- Matter: Anything that occupies space and has mass.
- Energy: Ability to do work or cause change.
- Force: Push or pull that causes an object to change its motion.
- Mass: Measure of the amount of matter in an object.
Laws of Physics
- Law of Universal Gravitation: Every point mass attracts every other point mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
-
Newton's Laws of Motion:
- First Law: An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
- Second Law: The force applied to an object is equal to the mass of the object multiplied by its acceleration.
- Third Law: For every action, there is an equal and opposite reaction.
- Conservation of Energy: The total energy of an isolated system remains constant over time.
- Conservation of Momentum: The total momentum of an isolated system remains constant over time.
Key Physicists
- Isaac Newton: Developed laws of motion and universal gravitation.
- Albert Einstein: Developed theory of relativity and famous equation E=mc^2.
- Marie Curie: Discovered radioactive elements and pioneered radioactivity research.
- Max Planck: Introduced concept of quantized energy and founded quantum theory.
- Galileo Galilei: Contributed to the development of modern physics and astronomy.
