Light and Sound
The spectrum of light we can see
What is Visible Light
Dropped two cannon balls off of the Leaning Tower of Pisa.
Who is Galileo?
Energy that comes from chemical reactions
What is Chemical Energy?
Caused by an unequal number of electrons spinning in opposite directions
What is a magnet?
Energy that has the potential of doing work.
What is Potential Energy?
The frequency difference in sound
What is Pitch?
An object in motion will stay in motion unless something acts upon it.
What is Newton's First Law?
When chemical energy is converted to energy of motion.
What is mechanical energy?
These two poles repel each other
What are like poles?
The Energy of Motion
Sound intensity measurement
What are Decibles
Statements that tell us about how the physical world around us works.
What is physical laws?
A common way to store chemical energy.
What is a battery?
An electric current that runs though a wire creates a magnetic field which creates this.
The force something has based on its mass and speed.
What is Momentum?
What is amplitude?
Newton's law that tells us why we stay firmly on the surface of the Earth.
Can be shown by placing a magnet in iron filings.
What is a magnetic field?
The tendency of things to resist a change in motion.
What is Inertia?
The distance between wave peaks
What is wavelength
The process by which we make scientific discoveries.
What is the Scientific Method?
When one atom splits giving off more neutrons which make more atoms split.
When something magnetic causes another objects extra electrons to spin in one direction making it magnetic also.
What is magnetic induction?
A force that tends to slow objects down.
What is friction?
