1. Displacement: This refers to the change in position of an object. It's a vector quantity, meaning it has both magnitude (how far the object moved) and direction.
2. Velocity: This describes the rate of change of an object's displacement over time. It's also a vector quantity, indicating both the speed (how fast the object is moving) and the direction of motion.
While acceleration is a crucial concept in linear motion, it's derived from these two fundamental concepts. Acceleration is the rate of change of velocity over time.
