Which is the best example of potential energy?
Old photographic flashbulbs burn magnesium metal in a reaction that causes a flash of brilliant white light. A photographer would need to take care not to suffer burned fingers when trying to replace the hot bulb. What best identifies the energy transformation that occurs in the flashbulb?
When an object falls toward the ground due to gravity, what type of energy becomes kinetic energy?
A cyclist eats a full meal before going to ride a bike for 2 hours. Which energy transformation happens during this process?
Which is the best term to use when describing the energy of motion?
Which energy change best relates to a boulder that is rolling down the side of a hill?
Which statement describes thermal energy?
Chemical energy in burning wood is changed into thermal energy. The thermal energy is absorbed by water, which boils to produce steam. The thermal energy is changed into kinetic energy in the moving steam. The kinetic energy is used to turn a turbine, which converts the kinetic energy into electricity. Which sentence best describes this system?
Which form of energy is directly related to the measure of the average kinetic energy of the particles in a substance?
