5-7-Physics Review

Transfer, Sound and Thermal Energies

QuestionAnswer
What is a system? Objects that work together
In a system, when the energy in one object decreases, the energy in another part Increases
Thermal energy is the total kinetic energy of an object's molecules due to their random motion.
The factors of thermal energy are Mass and Temperature
When an object emits sound... it loses some of its energy to the surroundings
When two balls are bounced with one on the top of the other, the bottom ball bottom ball's energy decreases
Why does an object stop? All energy has been transferred out.
The particles in a warm object move ___________ than the particles in a "cold" object faster
Potential energy is stored energy that results from the position or shape of an object
Sound transports by oscillating like a wave through medium (material)
The states of matter that sound can travel through are solids, liquids and gasses.
Sound energy travels the most efficiently through Solids
Dolphins and Bats are alike because they use echolocation to find their prey.
