•   Rest and Motion: Differentiate between objects at rest and in motion.

•   Displacement: Dive into the concept of displacement and its distinction from distance.

•   Velocity: Master the definition and calculation of velocity, understanding its different types (scalar and vector).

•    Acceleration: Explore the concept of acceleration and its role in changing velocity.

•    Types of Motions: Identify and understand various types of motion, including linear, circular, and oscillatory.

•    Speed: Grasp the difference between speed and velocity, and learn how to calculate speed.

•    Equations of Motion: Apply these powerful equations to solve motion-related problems.
