A push or a pull
Sound energy travels in _________ waves.
Compression waves
What is it called when something goes from a SOLID to a LIQUID?
Melting (think of an ice cube)
Light energy is also called _______ energy.
Light energy is also called RADIANT energy.
What is the only type of visible energy?
Light/radiant energy
A biker rides UP and OVER a hill. When do they have POTENTIAL energy?
At the very top! Potential energy = stored energy that has the potential to move.
Why can sound not travel through space?
Because space is a vacuum which means there is no matter (medium) for the sound every to travel through
Matter is anything that has _____ and takes up _____.
Matter is anything that has MASS and takes up SPACE.
Name each color in ROYGBIV.
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Energy cannot be created or destroyed, it can only ________.
Transform
(This is the Law of Conservation of Energy!)
Ms. Kim throws a tennis ball that weighs 1kg and Mr. Kavoori throws a basketball that weighs 5 kg. Which one needs MORE force to travel the same distance?
The basketball needs more force because it has more MASS.
Sound travels through which type of matter the FASTEST? Why?
Sound travels through SOLIDS the fastest because the atoms are the closest together for the vibration to pass through.
Trail mix with peanuts, raisins, and M&Ms is an example of a (mixture / solution).
A MIXTURE. A mixture is a combination of two or more substances that can be EASILY separated
Light moves in __________ waves.
Which 2 types of energy are involved in the energy transformation that occurs when solar panels are used to heat a building?
(______ energy ---> ______ energy)
Radiant → thermal
When there is an unbalanced force acting on an object that means that the object is __________.
in MOTION! The object moves in the direction of the stronger force (push or pull).
Because of the vibrations, sound energy is also a type of _________ energy.
Mechanical energy! Mechanical energy is the energy of MOTION, and vibration is motion.
Ms. Merritt wants to make some tea so she puts a tea kettle full of water on the stove and turns the heat on high.
What happens to the ATOMS in the water as they start to heat up?
The atoms in the water start to move FASTER until they tern into a gas (steam!)
REFRACTION is when light energy hits matter and (bounces / bends).
BENDS. An example of refraction is the pencil in the water station.
Energy is the ability to do _______ and cause _______.
Energy is the ability to do WORK and cause CHANGE.
To describe the motion of a tennis ball, you should include its _______ and ________.
Speed and direction
The shorter the wavelength, the ____________ (higher or lower) pitch of the sound
Higher
Which will have MORE mass: An ice cube when it is frozen or the same ice cube when it is melted?
They will have the SAME mass!
The Law of Conservation of Mass tells us that matter is not created or destroyed when it changes states.
Which color of ROYGBIV has the LOWEST frequency?
RED! Red has:
- The lowest frequency
- The longest wavelength (it looks the flattest)
- The least amount of energy
