This video tutorial explains how to calculate kinetic energy using the formula KE = MV^2/2, where M is mass in kilograms and V is velocity in meters per second. It emphasizes the importance of following the order of operations, particularly squaring the velocity first. The tutorial includes two examples: calculating the kinetic energy of a car and a baseball, demonstrating the step-by-step process of plugging values into the formula and solving for kinetic energy. The video also highlights the significance of using correct units and understanding the concept of kinetic energy.
