What is kinetic energy?

Energy of Motion

100

What is a longitudinal wave?

Sound waves

100

What is conduction?

Transfer by touch

100

What is an independent variable?

The variable that changes

When my clothes are in the dryer and I feel static on them, where did that come from?

Friction. The clothes rubbed against each other


200

What is potential energy?

Stored energy,

200

If my wave has high frequency, high amplitude, low wavelength, does it have high or low energy?

high energy

200

What is convection?

Transfer of heat through water and gas

200
What is an educated guess in science?

A hypothesis

300

Contact or Non-Contact: Magnetic Force

Non-Contact


300

What is the law of conservation of energy?

Energy cannot be created or destroyed only transferred or transformed

300

Where does a sound wave travel the fastest? The slowest? 

Solid is the fastest, Gas is the slowest.
300

What is radiation?

Transfer of heat through waves from the sun and light

300

Can laws change? Why or Why not?

Laws cannot change. They explain what happens, not why. Example, law of gravity. I do not want to see when this changes.
400

What forces are affected by distance and mass?

Gravity & Magnetism

When I was at Busch Gardens, I rode Sheikra, and it was scary. What energy transformation is seen in this example when Sheikra goes up and down the hill.

Gravitational potential energy is seen when it goes up the hill, and then it transforms into kinetic as it drops.

What is a transverse wave?

Light wave

If Antawn is trying to figure out which scissors are the best to cut open a metal rod. He tries 5 types of scissors and writes down if they cut the rod open. What is the dependent variable of the lab?

If the rod was cut open or not.

Name all of the contact forces and non-contact forces>

Contact: Friction, Applied, Normal and Air Resistance.


Non-Contact: Gravitational, Electrostatic, and Magnetism

500

What is energy?

The ability to do work

Does a gamma wave that is highly dangerous for us to be around, have high energy or low energy? What about a radio wave?

Radio wave: low

Gamma: high

When my sister makes rice, she burns it really bad and it sticks to the bottom of the pot. What heat transfer caused the rice to turn black and stick to the bottom of the pot?

Conduction

What is a limit model of the solar system?

The limit of this model is it does not show me the real size of the planets.
