2. MOTION IN A STRAIGHT LINE

Motion is defined as the change in position of an object concerning time. This chapter discusses various aspects of motion, focusing on concepts like velocity, acceleration, and kinematic equations for uniformly accelerated motion. The relationships between these concepts are explored through practical examples and theoretical explanations, culminating in an understanding of relative velocity.
