Study Notes
Fundamental Forces in Physics
- There are four fundamental forces in physics: gravity, electromagnetism, strong nuclear force, and weak nuclear force.
Vector Quantities
- Scalars have only magnitude, while vectors have both magnitude and direction.
- Examples of vector quantities include displacement, velocity, acceleration, and force.
SI Units
- The SI unit of electric charge is the coulomb (C).
Newton's Laws
- Newton's second law of motion states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration, expressed as F = ma.
