Study Notes

Scalars and Vectors

  • A scalar quantity is an example of a magnitude with no direction, such as temperature, mass, or density.
  • A vector quantity is characterized by both magnitude and direction, such as displacement, velocity, or acceleration.

Fields in Physics

  • A field in physics is a mathematical construct that represents a distribution of quantity or property over a region of space, such as electric, magnetic, or gravitational fields.
