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.
