potential energy (PE) - stored energy due to position of objects or arrangement of particles; CANNOT be transferred BUT, CAN be transformed, kinetic energy (KE) - energy in motion; CAN be transferred & transformed, Gravitational PE - potential energy that depends on an object’s mass and its height above the ground, Elastic PE - energy stored in objects that can be stretched or compressed, such as trampolines, rubber bands and bungee cords, Chemical PE - energy stored in the arrangement of particles such as in food, fossil fuels, etc., Law of the Conservation of Energy - energy cannot be created nor destroyed; it can only be transformed and transferred, total energy of a system - the sum of the potential and kinetic energies;, energy transformation - energy conversion, energy transfer - energy is relocated from one system to another, photosynthesis - light (radiant, electromagnetic) energy → chemical energy with heat “lost” to surrounding, waves - disruptions that transfer energy from one place to another; do NOT transfer matter, transverse waves - waves where the particles in the medium move perpendicular to the direction of the energy, longitudinal waves - waves where the particles of the medium move in the same direction (parallel) as the energy,
