Study Notes
Motion Fundamentals
- Projectile motion requires a minimum of 2 dimensions to describe it (x and y coordinates).
Vector Quantities
- A vector quantity is a physical quantity that has both magnitude (amount of movement) and direction.
Units and Dimensions
- The unit of acceleration in the SI system is meters per second squared (m/s²).
- Time is a dimension, and its unit in the SI system is the second (s).
Types of Motion
- Rectilinear motion is a type of motion where an object moves in a straight line.
