What is a collision?
When objects collide or hit one another.
100
What does energy transformation mean?
When one type of energy is converted or transferred to another type.
100
What is speed?
How fast an object is moving.
200
Can energy be created or destroyed?
No, energy can only be transferred.
200
A battery uses what kind of energy?
Chemical energy.
200
What happens when two objects collide?
Motion of energy is transferred from both objects, causing them to change directions or stop.
200
Name the energy transfer that takes place in a toaster.
Electrical energy converts to heat energy.

Josie and Charlie are racing cars down different sloped ramps. Josie's car traveled down Slope A and Charlie's traveled down Slope B. Josie's car traveled further than Charlie's. Charlie wants to beat her in the next trial. What can he do to his ramp to make his car travel further?
Charlie would need to build a steeper ramp.
300
What is evidence?
Anything that helps prove or disprove an idea.
300
Name the energy forms that occur when a firework goes off in the sky.
Light, sound, heat, chemical.
300
How does weight affect a car collision?
The more weight the car has, the more energy it will have to move the other car backwards.
300
Where would you find the most potential and kinetic energy on a rollercoaster?
Potential would be on the top of the hill before it goes down. Kinetic would be as gravity takes the car down a hill.
300
____________ is a measure of how fast an object is moving, and __________ is a measure of how far apart objects are.
Speed, distance
400
What is the definition of position?
Where something is in space.
400
What happens when you switch a light switch on and off? (Use vocabulary words)
Electrical energy is being transferred to light energy through a circuit which is broken when the light switches off.
400
How does the height of a ramp affect a collision?
The taller the ramp, the more kinetic energy that the car will posses, causing a larger impact.
400
Name a device that provides evidence that electrical energy can be converted to light energy and sound energy
A computer
Doorbell
Etc.

Shakira ordered two bowling balls of the same size and type. She bought one pink ball and one orange ball. Shakira rolled each ball down the same lane at the bowling alley one time while a friend used her phone timer to measure the time it took for the balls to travel to the end of the lane. After rolling both balls down the same lane one time, they noticed that the pink ball made it to the end of the lane faster than the orange ball.
Which is the most likely reason that the pink ball moved faster than the orange ball?
The pink ball probably had more force behind it.
500
Energy that is stored is called what? Give an example of this.
Potential energy.
500
What is sound energy?
Energy that travels as waves through the air or water and vibrates the ear drum upon contact.
500
If I line up four pennies in a row, touching one another and take the first two and collide them into the line, what will happen?
The last two pennies will move forward because it's the same amount of energy transfer.
500
The energy transformation that takes place when a flashlight is turned on is...
Chemical to electrical to light
500
If Will were to go sledding on both of these hills, knowing his brother Joe would be on the bottom - what would be the difference between the two crashes? 
A crash on "The Dragon" would have more energy and speed associated with it because it is a steeper hill, so the impact would propel his brother, Joe forward a long distance.
