Waves
The lowest part of a wave.
trough
This is the method of heat transfer involved with fluids like ocean and/or gases like air.
What is convection?
The energy any object has because of its motion.
What is kinetic energy?
The variables that remain the same for all trial in an investigation so that the experiment can be VALID.
What are the constant variable?
Objects at high elevations have lower potential energy because gravity takes away their potential to fall much further.
What is false?
The highest part of a wave
crest
This is the method of energy transfer involved with direct contact to the heat source.
What is conduction?
Stored energy or energy that an object has due to its position.
What is potential energy?
Name the control to the following experiment. How does the amount of water effect the growth of a plant?
What is no water?
A name also given to light energy
What is radiant energy?
The part of a longitudinal wave where the particles of the medium are close together.
compression
We get this method of energy transfer from the sun.
What is radiation?
As a roller coaster car goes down a hill, its potential energy is changed into this.
What is kinetic energy?
If your hypothesis is proven correct this is the next step in the process.
What is repeat the test?
The amount of Potential Energy on an object depends on these two things.
What is mass and height from the ground?
It can't fix a car, but this does requires a medium through which to travel.
What is a mechanical wave?
Freezing occurs when a substance ____________ thermal energy. Loses or Gain?
What is loses?
Energy of the movement of atoms and molecules.
What is thermal energy?
The axis that is used to plot the responding/outcome variable.
What is the y axis?
Dark clothing keeps you warmer in cold weather because the dark color absorbs the sun's energy.
What is true?
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
What is a transverse wave?
When gas loses a sufficient amount of thermal energy, it will change into a ______________. Give a state of matter.
What is a liquid?
This is an example of radiant energy being changed to chemical energy.
What is photosynthesis?
DAILY DOUBLE: How does parachute size effect the rate of a falling object? The independent variable. The dependent variable.
What is the size of the parachute? What is the rate of a falling object?
Why do some pots have a layer of copper at the bottom? a. copper is a good conductor of heat. b. copper creates convection, which heats food. c. copper increases the pot's mechanical energy. d. copper is an insulator that keeps food from burning.
What is a. copper is a good conductor of heat.
