Correcto: Mechanical energy = Potential + kinetic energy, There are 3 types of materials: opaque, transparent and translucent, Reflection is when light bounces off a surface, Sound vibrations travel very slowly, The timbre of the sound is the tone the sound produces, Radiation is the transfer of thermal energy from the Sun through waves, Renewable sources of energy are unlimited, Incorrecto: Light can travel through wood, Light can't travel through clear glass, Separation is when light bounces off a surface, Sound vibrations can't travel through different materials, The loudness is how high or low the sound is , Convection is a direct transfer of thermal energy through contact, Non-renewable sources of energy are unlimited,
