This is produced when electrons move through a circuit.
Electricity (What is electricity?)
Microwaves (what are microwaves)
materials through which heat and electricity transmits through easily
A conductor (what is a conductor?)
any push or a pull on a object
Force (what is a force?)
The Kinetic Energy formula
any material that attracts or repels iron/steel/nickel etc.
True or False: Radio waves ALONE can do enough damage to seriously hurt a person.
False-- Radio waves alone do not carry enough energy to harm someone.
materials that prevent electric charges from flowing through them easily
Insulator (what is an insulator?)
The only type of force that can cause motion
Unbalanced (what are unbalanced forces?)
The three parts of an atom
Proton, Neutron, Electron (What are protons, neutrons, and electrons?)
The interaction between electricity and magnetism
Electromagnetism (what is electromagnetism?)
The EM spectrum in order from weakest wave to strongest.
Radio, Micro, Infrared, Visible Light, UV, X-Ray, Gamma (What is... ?)
Name every type of energy defined by M.E.L.T.S --
Mechanical, Electrical, Light, Thermal, Sound (what is....?)
What is the unit/measurement for the FORCE of an object?
Newtons or "N" (What are newtons?)
The formula for gravitational potential energy. Explain what each variable stands for.
m = mass
g = gravity (9.8)
h = height
True or False: Gravity will pull "harder" on an individual standing on the ground compared to someone standing at a higher elevation.
FALSE -- The person standing higher up (high elevation) will have a higher GPE (gravitational potential energy).
The difference between mechanical waves and EM waves.
Mechanical waves can be FELT and need a medium to travel. EM waves do not.
True or False: Energy is not carried by waves, but they are the same thing.
False -- Energy IS carried by waves, and they ARE NOT the same thing.
Write the speed formula. Calculate the speed of an object that travelled 1200 miles in 20 hours.
Speed = Distance / Time
1200/20 = 60 miles per hour.
Calculate the GPE of a man who weighs 48 kilograms and who is standing 20 feet off of the ground.
9,408 joules. (What is 9,408 joules?)
How does the rotational force of gravity affect the seasons on Planet Earth?
Earth rotates around the Sun, this determines which season it is by controlling what side of the planet is facing towards the Sun (Summer) or away from the Sun (Winter)
Place the colors of the Visible Light spectrum in order from STRONGEST/HIGHEST FREQUENCY to WEAKEST/LOWEST FREQUENCY.
V. I. B. G. Y. O. R
Which type of energy is obtained from breaking apart an atom? Would it be considered a type of potential energy or a type of kinetic?
Nuclear Energy-- Which is a type of potential energy.
Calculate the slope between the following two points: (2, 4) and (8, 6).
SHOW ALL WORK.
m = 3 (What is m= 3)
Use algebra to derive a formula of Kinetic Energy from the Mechanical Energy formula.
ME = KE + PE
- PE - PE
