1. Velocity: This describes the rate of change of an object's position over time. It has both magnitude (speed) and direction. For example, 5 meters per second north.
2. Acceleration: This describes the rate of change of an object's velocity over time. It also has both magnitude and direction. For example, 2 meters per second squared downward.
These two quantities are essential for understanding how objects move and are related to each other through Newton's laws of motion.
