Example- When you do positive work, you add energy to an object. If you throw a ball, you increase its velocity and add to its kinetic energy. If you lift a ball, you increase the distance gravity can pull it and add to its potential energy. If you drop a ball, gravity does work and changes the ball’s potential energy to kinetic energy.
Over the last few science lessons, students have been working to develop their understanding of potential and kinetic energy. As a result of their investigations, students have come to understand the key differences of the two forms of energy. Potential energy is energy that is stored in the position, or structure, of an object. Potential energy can be increased by increasing the height and/or the mass of the object. Kinetic energy is the energy of a moving object. Kinetic energy can be increased by increasing the speed and/or the mass of the object.

AuthorMy name is Mr. Bliven and I have been teaching at Matsunaga for 13 years. I love teaching and view education as a lifelong journey. Although I already hold several graduate degrees from McDaniel College and Johns Hopkins, I was thrilled to have recently completed my graduate certificate in technology integration from the University of Florida. I plan to continue my graduate studies and I am looking forward to using the strategies that I learn with my students. Archives
