Newton's 1st law states that an object in motion stays in motion unless acted upon by a force. If I roll a yoga ball on the carpet, why does it eventually stop? What is the force?
The force is the friction produced by the surface (carpet.)
-A television
-An Alarm Clock
-A trombone
-Fireworks

After building a bird house, Solana wants to seperate the metal from the wood shavings to properly dispose of them. What is one way she could separate the metal shavings from the wood pieces without sorting them by hand?
She could use a magnet.
What would cause more friction- sliding a book on carpet or ice? Why?
Carpet. Ice has a smoother surface than carpet.
Describe the energy transformation that happens when you use a blender that is plugged in.
Electrical energy transforms into mechanical energy and sound.
What is refraction
Light goes through a substance and bends.
Ms. Dillard, Mrs. Fowler, Ms. Brown, and Mr. McDaniel tried to push a giant boulder. None of them were able to move the giant rock at all. Was work done to the boulder?
No. For work to be done the object has to move in the direction of the force.

a. A car that is slowing down at a red light
Describe the energy transformation that occurs in a solar panel.
Light energy transforms into electrical energy.
What is a conductor and how is it different from an insulator?
A conductor allows energy to go through it. An insulator slows down or stops the flow of energy.
