Track and visualize how energy flows and changes through your system. Explore how heating and cooling iron, brick, water, and olive oil adds or removes energy. See how energy is transferred between objects.
The LOL Charts Concept Builder provides students with a rigorous exercise in conducting an energy analysis in order to construct a bar chart that demonstrates how energy is stored, transferred, and/or conserved by a system undergoing a change between two states of motion.
Use this worksheet to create diagrams having to do with various mechanics situations. Masses, pulleys, inclines, springs, pulleys, and more are available to be used in custom made diagrams.
Use three pre-designed tracks or design your own. Let the car roll and watch as energy changes form and force, accceleration, and velocity vectors change their size and direction. Explore on your own or use The Physics Classroom's ready-to-use exercise. Now available with a Concept Checker.
Explore how energy flows and changes through heating, cooling, and transferring between different objects with this interactive simulation.
Work on one of the 3 following packets: # 1 - Focuses on how to calculate energies. # 2 - Focuses less on how to calculate energy and more on using LOL charts to solve Problems. # 3 - MAIN focus is using LOL Charts to solve more complex problems.
practice. The diagram below shows a 10,000 kg bus traveling on a straight road which rises and falls. The horizontal dimension has been foreshortened. The speed of the bus at point A is 26.82 m/s (60 mph). The engine has been disengaged and the bus is coasting. Friction and air resistance are assumed negligible.
