If a soccer player kicks a soccer ball hard, are they using a lot of energy or not much energy?
A lot of energy.
100
What is transferred when objects collide?
Energy.
100
What happens to a ping pong ball in a water tank? 
It bobs up and down.
100
What are sound waves caused by?
Vibration.
100
What is our planet's main source of light?
The sun.
200
An object moving ________ uses only a small amount of energy.
Slowly.
200
When traveling the same speed, which will have more energy, a large object or a smaller object?
A large object has more energy because it has more mass, so it has more energy and will be harder to stop than the smaller object.
200
Which is transferred in a wave, energy or matter?
Energy.
200
Name 2 mediums sound waves can travel through?
Air.
Liquids.
Solids.
200
Name 2 examples of Light Producers.
Light bulbs. Car headlights. Outdoor fires. Fireflies. Flashlight. Fireworks.
300
If you roll 2 balls the same size, one with more energy and one softly, what will happen?
The more energy will go faster, the soft one with less energy will move slower.
300
What happens when a moving object collides with another moving object?
Both objects change direction or stop.
300
What is amplitude of a wave?
Amplitude is the height of a wave from its base.
300
Do Sound waves travel faster or slower underwater than they do in the air?
Sound waves travel 4.3 times faster underwater than they do in the air, and they retain their energy for much longer.
300
Which light wave is a mirror?
a. Diffusion. b. Refraction. c. Reflection.
c. Reflection.
400
Does the picture show potential or kinetic energy?
Kinetic. It's MOVING energy.
400
Why might we hear a loud sound when 2 objects collide?
When 2 objects collide, energy is transferred and will cause sound energy and heat energy energy.
400
What is the distance between wave peaks called?
It's called wave length.
400
Can sound waves travel in outer space?
No. There are no air particles to travel through.
400
Define transparent, translucent, and opaque materials. 
Transparent materials allow light to pass through, enabling clear visibility through them; translucent materials allow light to pass through but scatter it, making objects behind them indistinct; and opaque materials block light entirely, preventing any light transmission.
500
Which will move more quickly, a ball at the top of a hill or a ball from the middle of the hill?
Ball 1, at the top of the hill.
500
What happens when a moving ball collides with a non-moving object like a wall? 
The moving object transfers its energy, causing the non-moving object to move or change direction.
500
What is the difference between a longitudinal wave and a transverse wave?
A longitudinal wave travels in one direction. A transverse wave moves up and down.
500
Why is sound important to marine animals? 
Sound is crucial for marine animals, enabling communication, navigation, and finding food.

When you see a blue car, what color(s) are repelled and what colors are absorbed?
Blue is reflected. All other colors are absorbed.
