Forms of Energy
What two groups are all the several types of energy put into?
Potential energy or Kinetic energy.
What is the definition of force?
A force can determine and cause an object to change its velocity and/or acceleration.
What is Convection?
A process by which heat is transferred by movement of a heated fluid.
What is a streak test?
A streak test is conducted by scraping the edge of a mineral across a piece of porcelain, also known as a “streak plate.”
What is a chemical reaction?
A chemical reaction occurs when one or more substances are converted to one or more different substances.
What are five types of energy?
Thermal, Chemical, Nuclear, Electrical, Radiant, Light, Motion, Sound, Elastic, Gravitational energy.
What is Newtons Second Law?
The Law of Motion - F = M x A
Forces = Mass times Acceleration.
What is radiation?
Energy that comes from a source and travels through space at the speed of light. Also known as electromagnetic waves.
What is thermal contraction?
Thermal contraction occurs when materials are subjected to a decrease in temperature.
What is the product of a chemical reaction?
The product of a chemical reaction is the substance produced at the end.
What is the Law of the Conservation of Energy?
This law states that energy can never be created or destroyed but can be transformed into different types of energy.
What are some examples of force?
Applied, Gravitational, Normal, Frictional, Air Resistance, Tension and Spring are all examples of forces.
What are the three ways of heat transfer?
Convection, conduction, and radiation.
What is the difference between a compound and a mixture?
Compounds are substances which can be formed by chemically combining two or more elements. Mixtures are substances formed by physically mixing two or more substances.
What are the substances that go into the chemical reaction called?
Reactants
What is Energy Transformation?
Energy transformation is the process of changing energy from one form to a different form.
What energy is being changed when a ball is rolling down a hill?
Potential energy to Kinetic energy.
What is the difference between convection and conduction?
In convection, the heat transfer takes up the liquid. In conduction, heat transfer occurs between objects that come in direct touch with one another.
Whats the difference between a physical property and a chemical property?
A physical property is any characteristic that can be determined without changing the substance's chemical identity. A chemical property is any characteristic that can be determined only by changing its molecular structure.
What are five common chemical reactions?
Combination reaction, Decomposition reaction, Displacement reaction, Double Displacement reaction, and Precipitation reaction.
Is Chemical energy considered as potential or kinetic energy?
Potential energy
What is the difference between balanced and unbalanced forces?
Balanced forces are equal in magnitude but are opposite in directions. Unbalanced forces are forces that are not equal in magnitude but may or may not act in the same direction.
What is a wireless power transfer?
The transmission of electrical energy from a power source to an electrical load, without the use of man-made conductors.
What are five physical properties?
Density, Color, Luster, Magnetism, Texture, Melting Point, Conductivity, Elasticity, Malleability, and Ductility.
What type of reaction is it when hydrogen and chloride mix to create hydrochloric acid?
Combination reaction.
