Study Notes
Describing Motion
- To describe the motion of an object along a straight line, three physical quantities are necessary: position, velocity, and acceleration.
Dimensions and Vectors
- One dimension has only one possible dimension.
- Vectors are needed to describe the motion of an object in two or three dimensions.
Motion in Multiple Dimensions
- To describe motion in two or three dimensions, it is necessary to learn vector algebra and how to resolve vectors into components.
Directional Aspect in One Dimension
- To take care of the directional aspect of physical quantities in one dimension, a positive or negative sign is used to indicate the direction of the quantity.
