Forms of Energy
What type of energy comes from a fire?
Heat energy
What kind of path does light travel in?
Straight Lines
What happens when light bounces off of an object?
Reflection
Energy that is being stored is called what?
Potential
What is it called when energy moves from one object to another?
Energy transfer
What type of energy do you hear when someone plays music?
Sound energy
What do we call materials that lets light pass through easily, like glass?
Transparent
What happens when light bends as it passes through materials?
Refraction
Kinetic
What color of paper does light absorb more of and why?
Darker colors - They are darker colors, so they absorb more light. The lighter colors allow more light to pass through.
What type of energy comes from the sun?
Light energy
What do we call materials that block all light?
Opaque
Mirror
When a roller coaster is at the top of a hill, it's called what?
Potential Energy
Where do humans get our energy from?
What type of energy do moving objects have?
Kinetic Energy
What do we call materials that only let some light through, like tissue paper?
Translucent
Give an example of refraction in our everyday lives?
Straw in a glass filled with water
When the roller coaster is going down the hill, it's called what?
Kinetic Energy
Why does the rubber band make a louder noise on the tissue box when you pull it higher?
Because it is storing more energy, then releases it all to make a louder noise.
What type of energy do we use to power lights in our homes?
Electrical Energy
Describe the angle that light takes when it is being reflected off of something.
Angle in = Angle out. The light bounces off at the same angle it is coming in at.
Why does a pencil look broken when it is in a glass of water?
Because the light bends (refracts) as it moves through the water.
What type of energy is it when a moving object hits a non-moving object?
Mechanical
When you drop a ball, describe the energy transfer that happens?
Potential energy changes to kinetic as it falls.
