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.

What is the acceleration due to gravity on Earth?

How does the direction of acceleration differ between horizontal and vertical motion?

Explain the significance of negative signs in the equations of motion.

How long does it take for a rock dropped from a 100 meter cliff to hit the ground?

What happens to the velocity of an object thrown upwards due to gravity?

Describe the process of using the quadratic equation in the context of vertical motion.

What is the final velocity of a rock thrown upwards with an initial velocity of 10 meters per second when it hits the ground?
