Energy Transformations
Energy can not be created or destroyed; it can only be transformed or transferred to another object.
What is The Law of Conservation of Energy.
The energy of motion
What is Kinetic Energy?
Stored Energy.
absorb energy from their surroundings
What is Endothermic?
The sum of potential and kinetic energy in a system.
What is mechanical energy?
A lamp transforms __________ energy into light and thermal energy.
KE=1/2mv2
What is the equation for Kinetic Energy?
__________ causes Gravitational Potential Energy to increase.
What is height?
Releases energy to their surroundings
What is an exothermic process?
An _________ system can exchange both matter and energy with its surroundings. Energy and matter can flow in and out of the system.
What is open?
The mechanical(total) amount of energy in a closed system will remain ___________.
What is constant?
__________ and __________ cause Kinetic Energy to increase.
What is mass and speed/velocity?
Stored energy due to an object's position above the ground.
What is GPE?
Heat transfer through electromagnetic waves.
What is radiation?
A ___________system does not exchange matter or energy with its surroundings. Energy and matter stay within the system boundaries.
A candle's energy transformation turns __________ energy into thermal and radiant energy.
What is chemical energy?
If a bowling ball, a tennis ball, and a golf ball are all traveling at the same speed, which has the most KE?
What is a Bowling ball?
Energy is stored in bonds between atoms or molecules.
What is Chemical Potential Energy?
is heat transfer through direct contact between objects or particles. Heat moves from the warmer object to the cooler object when they touch.
Energy that seems "lost" is actually _________ into other forms, often heat. In Exothermic systems, energy is "lost" to its surroundings (environment).
What is transformed/transferred?
Heat transfer only takes place when there is a difference in ______________. Heat will ___________ transfer from a place of high temperature to a place of low temperature.
What is temperature and always?
Heat/ ________ energy is a form of kinetic energy.
What is thermal energy?
Which has the highest GPE, the top shelf or the bottom?
What is Top shelf?
Heat transfer through the movement of fluids (liquids and gases).
What is Convection?
Where is the potential energy on a pendulum the greatest, and where is the kinetic energy the greatest?
What is when you pull back the pendulum/ at the bottom?
