Study Notes
Scalar Quantities
- Scalar quantities possess only magnitude with no directional component.
- Examples include:
- Length
- Mass
- Time
- Distance
- Volume
- Density
- Temperature
- Speed
Vector Quantities
- Vector quantities are defined by both magnitude and direction.
- They play a significant role in understanding physical phenomena where direction matters.
Unit Vector
- A unit vector is characterized by a magnitude of one.
- It indicates direction without affecting the scale of measurement.
Equal Vectors
- Equal vectors are defined as vectors that are parallel, share the same direction, and have identical magnitudes.
- They represent the same physical quantity despite location differences.
Like Vectors
- Like vectors are parallel and have the same direction (sense) but differ in magnitude.
- They provide insight into forces acting in the same direction but with varying strengths.
