Vocabulary I
What is Gravity?
A force of attraction between objects that is due to their masses
What is energy?
The ability to do something
What is visible light?
Light you can visibly see
What is Kinetic Energy?
Energy of motion
Name 5 words associated with sound
Bing, Boing, Bang, Ding, Ting, Ring, Fah, Rah, Etc...
What is force?
A push or Pull exerted on an object
What is a wave?
A repeating pattern that transfers energy through matter or space
What is an example of infrared?
TV remotes, heat lamps, and heat emitted from the human body
What is the difference between Potential Energy and Kinetic energy?
KE - energy of motion
PE - energy stored up
In the egg drop experiment, what pulled your build down?
Gravity
What is Friction?
The resistance that one surfactant or object encounters when moving over another
What are the differences between balanced and unbalanced forces?
Balanced forces are equal in magnitude and opposite in direction, resulting in zero net force and no change in an object's motion (constant velocity or rest). Unbalanced forces are unequal, creating a non-zero net force that causes acceleration, deceleration, or a change in direction
What is a compass?
A navigational instrument that indicates the cardinal directions
What is the formula for Force?
F = MA
How do you make an oxidizing flame on a Bunsen burner?
You turn the collar
What is UV?
UVA, UVB, UVC
Ultraviolet light,
aging rays, burning rays, cancer rays
What is a wavelength?
The distance between two corresponding parts of a wave
What is radiation?
Transfer of thermal energy through waves
What are the formulas for KE and PE?
KE - 1/2mv^2
PE - MGH
Name the 4 Labs we need to know for our exam
Egg drop, electromagnet, sound waves lesson/lab, flame experiments
What are the 3 Laws of Motion made by Sir Issac Newton?
1. An object at rest stays at rest
2. More mass increases acceleration
3. For every action there is an equal opposition reaction
What are all of the properties of a wave?
Amplitude, wavelength, frequency, and speed
Define the 4 methods of electric charge
Conduction - Movement of charge by direct contact
Induction - Objects become charged without touching
Polarization - Electrons only move to the opposite side of their atoms rather than to the opposite
Friction - The resistance that one surface or object encounters when moving on another
What are two pictures that describe KE and PE?
PE - Roller coaster, slingshot being pulled, bow and arrow, and dam holding In water
KE - anything displaying motion
Name the steps to turn on and make the Bunsen burner light
first connect it to the gas source, close the air collar, and turn the gas on. Use a sparker (striker) above the barrel to ignite the gas, creating a visible yellow "safety" flame. Finally, adjust the air collar to achieve a hot blue flame
