Review over all units and subjects, includes a bit of intro, standard, and ACC.

QuestionAnswer
As voltage increases, current __________. Increases
Explain energy transformations within an open or closed system. Make sure to include chemical,mechanical, electromagnetic, light, sound, thermal, electric, potential, and kinetic energy. When energy is in a closed system it’s unable to transform into transform into other energies. When is energy is an open system it’s able to transform into other energies.
Give an example of energy transformations with these types of energy, and explain; chemical,mechanical, electromagnetic, light, sound, thermal, electric, potential, and kinetic energy. For example a battery starts with chemical when it’s put into a motor it goes from magnetic, to mechanical, to electrical.

Oglethorpe wanted debtors to be able to pay off the debt and start a new life. James Oglethorpe also hoped he would be able to expand their economy.
Explain the relationship between electricity,and magnetism. Their relationship is known as electromagnetism. This is when moving electrons create a magnetic field. So, an electric current can produce an electric and magnetic field.
How can an electromagnet be made? An electromagnet can create a electric and magnetic field by a wire be wrapped around an iron, connected to a voltage source.
How is a generator made? With a generator a magnet is placed in the center of the loop of wire and rotate freely. As the magnet rotates, the magnetic field produces an electric current in the loop of wire.
Define Motion. Movement of an object.
Define Mass. The amount of matter in an object.
Define Force. A push or pull applied to an object.
What would a graph for the relationship between mass and inertia look like? It would be increasing.
Explain how the electrons move in a series and parallel circuit. In a series circuit electrons flow in a single. In a parallel circuit electrons flow in multiple paths.
Explain the reasons for European exploration and settlement of North America, and the special interest of the Spanish and British in the southeastern area. The Spanish and the British were settled in North America to spread their religion, gain fame, and find gold. However, the British were mostly interested in raw materials so they can turn those into goods.

How did the cotton gin impact Georgia? Since the machine was efficient it lead to more slavery and became popular not only in Georgia but Southern States as well. The machine would later cause southern states to be dependent on agricultural.
How are mass and gravity related? As mass increases, gravitational attraction increases.
How are distance and gravity related? Inversely
