Energy Types and Transformations in Motion

Dr. Skateboard introduces a video series exploring physical science concepts in skateboarding and BMX. The video focuses on motion, explaining kinetic and potential energy through action sports. It describes how mechanical energy is the sum of kinetic and potential energy, using examples from skateboarding to illustrate energy transfer and conservation.
