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 conduction?
Ms. Amy hits a baseball and feels the bat shake in her hands, describing this law of Newton.
What is the third law of Newton (law of reactions)?
Ms. Arlinda is on a roller coaster that has a weight of 10,000 Newtons. It sits at the top of a 20-meter drop, giving it this much potential 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 convection?
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. L kicks a 2-kg ball at 8 m/s, giving it this much kinetic energy.
What is 64 J?
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?
What is radiation?
This is the only law of Newton that can be described as an equation.
What is the second law of Newton (law of acceleration)?
Ms. R puts a 100 N box on top of a shelf, giving it 200 J of potential energy. This is how high she put the box.
What is 2 m?
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 are conduction and convection?
This is an object's tendency to keep doing what it's doing.
What is inertia?
Mr. Davis throws a ball at 5 m/s with 50 J of kinetic energy. This would be its mass.
What is 4 kg?
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?
Ms. Delaney applies a force of 50 N to a 2-kilogram object. It should accelerate this much.
What is 25 m/s2?
