REFLECTION

Do you understand what is meant by the work done by a force? Do you know how to apply the work-kinetic energy principle? Do you know when mechanical energy is conserved? Do you know what information a graph of force versus distance gives? Can you describe the energy transfers taking place in various contexts? Can you solve problems with energy conservation?
