Waves
What wave type is parallel direction the wave travels
Longitudinal wave
What is Newton's first law?
If an object is at rest then it stays at rest and if a object is in motion then it stays in motion (with the same velocity) until it is moved by a unbalanced force.
What is the energy of movement?
Kinetic energy.
What is Au on the periodic table?
Gold
What is force?
A force is a push or pull that can change or maintain the motion of an object.
What are the highest and lowest points of a wave?
Crest as the highest and Trough as the lowest.
What is another name for Newton's first law?
The law of Inertia.
What is mechanical energy, the sum of?
Potential + Kinetic energy.
What atoms make up water?
One oxygen and two hydrogen atoms
What is one force you might experience when in the air? (FOR EXAMPLE: jumping)
Air resistance.
What wave is an earthquake usually?
Combined wave.
What is the formula for force?
F=MA
What is the measurement for work?
Joules (J).
What is the atomic number of gold?
79.
What is one form of friction?
I'll take Air resistance
What is the formula for wave speed? (Say what each symbol represents as well.)
v = fλ
V= speed and velocity of the waves
F= Frequency
λ=Wavelength
If two marbles were going to collide at the same speed, how would Newton's three laws affect it?
1st Law: Keeps the ball moving until the collision.
2nd Law: It affects the motion of the objects; the more force, the more it bounces back (Newton's third law). If one object had more acceleration than another, it could impact it more than the other object.
3rd Law: When the objects collide, they exert an equal but opposite force on each other, which is caused by the third law.
What is one example of Nuclear energy?
There are many, but one example would be the radiation from the sun
What two elements are in this compound? Table salt, NaCl.
Sodium Na and Chlorine (Cl)
If movenment is happening outside of a car what's a reference point that would make it so you aren't moving.
Your car, if your reference point was outside then yes you would be moving.
The frequency of a wave was 1 Hz= 1/s
What are all characterics that could describe the wave?
It's a pulse wave, nothing more because nothing else was given.
If two marbles that weighed 15 pounds were at the same speed 8 seconds before the collision what could possibly be possible reason that 2 seconds before they collided, they were at different speeds?
Friction, if one ball went over a coaster midway through, then it would lose speed. The coaster would also be the unbalanced force.
Height as well.
One sunny day, a man was eating some hot dogs while microwaiting some pizza, listening to the radio, and he started doing a workout that included jumping. A couple of hours later, it was thunderstorming, dropping the temperature to 32 degrees.
What are all the types of energy displayed in the short story, and where are they included?
Electromagnetic energy: Microwave.
Chemical energy: Food.
Sound energy: Radio.
Potential, Kinetic, Mechanical energy: Workout.
Electrical energy: Thunderstorm.
Thermal energy: Temperature.
What is H, N, O, F, and CI on the table?
Hydrogen, Nitrogen, Oxygen, Fluorine, and Chlorine.
Describe all forms of motion that happens when your jumping.
IDK I'll accept anything.
