Free Fall Motion Concepts

This video tutorial covers free fall calculations using acceleration formulas. It includes two problems: calculating the maximum height of a baseball and determining the velocity and displacement of a penny. The tutorial emphasizes identifying known variables and using appropriate formulas to solve for unknowns.
