Energy Forms
What is the easiest form of energy to see?
Mechanical
What kind of energy is due to motion?
Kinetic
What is any portion of the universe that one can select to study?
SYSTEM
What is work measured in?
Joules
What are the two ways Mechanical Energy is stored?
Gravitational Potential Energy (GPE) is the energy stored in an object due to its position above the ground. The higher and heavier the object, the more gravitational energy is stored.
Elastic Potential Energy is the energy stored in objects due to tension. Rubber bands, springs, sling shots, and archery bows are all examples.
What type of energy is stored in the bonds of atoms and molecules.
Chemical it is in the pancakes!
What kind of energy is due to position or state?
Potential
Do systems have boundaries?
Yes
What is a measure of the energy transfer that happens when an object is moved by an external force?
WORK
What energy travels in transverse waves?
Electromagnetic energy like SUNLIGHT
How is chemical energy released?
Chemical energy can be released or added during chemical changes (breaking and forming of chemical bonds).
What is a measure of a system's ability to change or move matter?
Energy
What form of potential energy has mass and due to its position in gravitational field?
Gravitational Potential Energy GPE
If an object does not move, was there work?
No, an object must move for there to be work.
What energy is the movement of particles (atoms and molecules) in a substance.
Thermal energy
Where is nuclear energy stored?
Nuclear energy is stored in the nucleus of an atom — the energy that holds the nucleus together.
If I have 50% Kinetic Energy how much Potential Energy do I have?
50% because they have to total 100%
When energy moves between systems, or between objects within a system it is called what?
Transfer of energy.
Work is equal to force times distance. True or False
True
Electrical energy is the movement of ______.
Electrons This is also known as "electricity"
What type of energy is the total energy of an object due to its motion and its position.
Mechanical energy
Can energy be transferred between objects during a collision like slapping hands?
Yes, it is Kinetic energy transferred.
What states that energy is neither created nor destroyed?
Law of conservation of energy
Can work be positive and negative?
Yes depending on whether there is an increase or decrease of the energy of an object.
What energy is the movement of energy through substances in the form of longitudinal/compression waves?
Sound Energy
