Mechanical Energy
Mechanical energy is made of these two types of energy.
What are potential and kinetic energy?
This describes a buildup of electrons.
What is an electric charge or electrical energy?
This describes how high or low a sound is.
What is pitch?
This describes when two solid objects transfer heat while in contact with each other.
What is by touch?
The tissue box on Ms. LaPierre's desk won't move unless you push it, describing this law of Newton.
What is the first law of Newton (law of inertia)?
Ms. Arlinda is on a roller coaster at rest at the top of a peak. It has 200,000 J of potential energy, giving it this much total mechanical energy.
What is 200,000 J?
Metals allow electricity to flow through them easily, making them these.
What are conductors?
Between gamma rays and microwaves, these have a higher frequency.
What are gamma rays?
When you get into a warm pool, you are having heat transferred this way.
What is through fluids?
A door is this kind of simple machine.
What is a lever?
Ms. L kicks a ball. It takes it 5 seconds to go 40 meters, meaning it has this velocity.
What is 8 m/s?
Ji Laoshi is holding a live wire that could shock her, but she has rubber gloves on, making the gloves this kind of object.
What is an insulator?
This describes the distance from the midline to the peak of a sound wave.
What is amplitude?
Your microwave oven cooks your food using this type of thermal energy transfer.
What is radiation?
This is an object's tendency to keep doing what it's doing.
What is inertia?
Ms. R drops a box. It has a total mechanical energy of 100 J. Partway down it has a potential energy of 60 J, giving it this much kinetic energy.
What is 40 J?
Fans, lights, and other things powered by electricity are drawn as this on circuit drawings.
What are resistors?
Plants convert light into chemical energy, describing this process of light.
What is absorption?
When cooking an egg, you put it in a hot pan and put a lid on top to trap in the steam, using these TWO types of thermal energy transfer.
What is by touch and through fluids?
This simple machine has another simple machine wrapped around it to make it what it is.
What is a screw?
Mr. Davis throws a ball at 5 m/s. 4 seconds later, it has gone this far.
What is 20 meters?
This kind of circuit allows 100% of the electrical energy to go to multiple resistors at the same time.
What is a parallel circuit?
Ms. Carmen sings a note at 140 Hz (waves per second) and Mr. Chris sings a note at 280 Hz, making these notes exactly this far apart in musical terms.
What is one octave?
This is the only way heat can be transferred through outer space between astronomical objects.
What is radiation?
The electron transport chain in your cells ends with a protein structure that spins when hydrogen ions are pushed through it, making it this kind of simple machine.
What is a wheel?
