Work is using force to move an object over a distance.

Slide 7 in power point
The peaks on the roller coaster are where the highest amounts of potential energy is. While the roller coaster travels between the two different points it is using kinetic energy.
100
This type of energy is energy you can see.
Light energy is energy we can see.
100
Name the two ways that light travels?
Light travels in a straight line and away from the light source.
100
What happens when a football player uses energy to kick a ball?
The balls kinetic energy changes.
200
When sitting at the top of the sledding hill I have this type of energy?
Before I start to slide down the hill I have potential energy.
200
Refer to power point 8
The girl on the high dive has more potential energy because she has a farther distance to use her kinetic energy on.
200
Describe this type of energy? (refer to youtube video)
This is sound energy. The sound energy has a high pitch because there are faster waves of sound.
300
The skier is going down the jump, what type of energy is showing here?
Once the skier starts going down the hill it turns into kinetic energy because he is in motion.
300
parking garage slide
Sound will bounce off the concrete. Bonus, what is this called?
300
Power point ( sound waves)
The top sound wave is a higher pitch because it is shorter and traveling faster. The bottom wave is a low pitch because it is slower and has a bigger distance between waves.
300
Decorated room Slide
Sound does not bounce off anything in this room. Instead it is being absorbed and weakened by the objects placed in the room.
400
What is energy?
Energy is the ability to do work or cause a change.
400
power point stripes
the stripes look like it is bent because light travels at a different speed through different matter. This is called refraction.
400
Tennis ball slide
The object blocking the light will create a shadow.
400
When I jump in a pool. Why does it feel cold?
The pool should feel cold because our bodies are warmer than the water in the pool.
400
power point slide
The light from the sun travels through the water droplets at a different speed. When this happens it is separated into all the colors that make white. This creates a rainbow.
500
This type of energy is the potential energy plus the kinetic energy of an object?
Mechanical energy is the energy that is the sum of potential energy and kinetic energy.
500
Power point about energy (katniss)
Pulling the string on the bow gives the arrow potential energy.Bonus: when does it change from potential to kinetic.
500
When does heat stop transferring?
Heat stops transferring when both objects are at the same temperatures. Example for bonus.
500
Define Conduction.
When heat is transferred by touch.

refer to power point 1
The spring has mechanical energy because it has both potential and kinetic energy.
