Kinematics - Motion Analysis Kinematics is a branch of physics that describes the motion of objects without considering the forces that cause the motion. It involves analyzing parameters like displacement, velocity, acceleration, and time. 1. Types of Motion ● Rectilinear Motion: Motion along a straight line. ● Curvilinear Motion: Motion along a curved path. ● Rotational Motion: Motion around a fixed axis. ● Projectile Motion: Motion in two dimensions under gravity. ● 2. Important Kinematic Equations For constant acceleration, we use the following equations: where: ● u = Initial velocity ● v= Final velocity ● a = Acceleration ● s= Displacement ● t= Time 3. Graphical Representation The following graph represents Velocity-Time relation: 4. Free Fall and Projectile Motion For free fall under gravity, the acceleration g is 9.8m/s^2. Equations for vertical motion: 5. Relative Motion Relative velocity is given by: 6. Uniform Circular Motion For motion in a circle of radius r at speed v: 7. Conclusion Kinematics provides essential tools to understand and analyze motion. It forms the foundation for studying dynamics, mechanics, and real-world applications in physics and engineering.
