Kinematics Part 2: Vertical Motion

The video tutorial explains vertical motion, focusing on the role of gravity as a constant acceleration of -9.8 m/s² on Earth. It covers the kinematic equations used to calculate time and velocity for objects in freefall and those with initial upward velocity. Two examples are provided: one where a rock is dropped from a cliff and another where a rock is thrown upwards. The tutorial emphasizes the importance of sign conventions in calculations and concludes with a comprehension check.
