What is velocity?
Speed AND direction
100
What is energy?
The ability to do work or cause change
100
What is a wave?
A traveling disturbance that transfers energy from one place to another but does not transfer matter
100
What is matter?
Anything that has mass and takes up space

You release a toy car down a ramp. The car eventually stops after rolling down the ramp. Which of Newton's Laws explains why the car stops?
Newton's First Law
(An object in motion stays in motion unless acted upon by an outside force. Sliding friction is the force acting against the motion of the car causing it to stop)
200
At what point on a roller coaster ride is there the greatest amount of potential energy?
At the highest point
200
What is reflection?
When a wave bounces off of a surface, changing direction
200
What are 2 physical properties and 2 chemical properties?
Physical: mass, volume, density, solubility, conductivity, boiling/melting point, magnetism
Chemical: burning, rotting, rusting

How do you spell Ms. Griffin's first name?
Micaela
300
What are the 3 types of forces?
friction, electricity, magnetism, gravity
300
What is the difference between conduction, convection and radiation?
Radiation is the transfer of thermal energy from one material to another by electromagnetic waves
Conduction: the transfer of thermal energy between materials by the collisions of particles (in contact)
Convection: the transfer of thermal energy by the movement of particles from one part of a material to another (in fluids)

What are the 6 parts of a communication system?

Explain how the electric force between a negatively charged balloon and small pieces of neutral (no charge) paper would be affected if you change the distance between the two from 5cm to 25cm (if the charge stays the same throughout). Why?
The strength of the electric force between the balloon and the paper pieces would decrease because the distance between them is increasing (distance and strength of electric force are inversely related)

Explain why, for a cooking pot, the pot itself is usually made of metal, while its handle is usually made of a plastic. (must use proper vocabulary to earn the points)
The metal pot allows thermal energy to flow through it easily so it is a thermal conductor. This allows the burner on the stove to heat up whatever is inside of the pot to cook it.
The handle of the pot is a thermal insulator. The material does not allow energy to flow through it easily. This allows you to touch the pot by the handle without burning yourself even when the contents in the pot are hot (it takes longer to become hot than the pot itself).

Why do you get a sunburn if you are out in the sun for too long without sunscreen, but your skin doesn't burn when you shine a flashlight on it?
Ultraviolet waves have a higher frequency than light waves. Higher frequency means more energy carried by the waves. So ultraviolet waves from the Sun carry enough energy to damage skin cells. Light waves (lower energy) from a flashlight do not.

Describe what happens to the state of matter of water when deposition occurs. Include kinetic and thermal energy in your answer.
Lots of thermal energy is removed quickly causing the particles to slow down, reducing kinetic energy, a lot and rapidly, resulting in the water changing from a gas to a solid

When is Ms. Griffin's birthday (month and day)?
November 5th

An in-line skater uses two hands to push forcefully against a wall in front of her. Explain why she rolls backward (there are 3 forces involved that you must explain).
The skater exerts an action force on the wall; the wall exerts a reaction force of equal size but in the opposite direction on the skater.
The reaction force is greater than the force of static friction on the skater, so the skater rolls backward, away from the wall.

A popcorn maker is plugged into the wall and then popcorn is made. You and your friends eat it for a snack. (hint, use 5 types of energy in your explanation)
Electrical energy from the popcorn maker being plugged in is converted into thermal energy when the energy is transferred to the heating element of the popcorn maker. The thermal energy is transformed into mechanical energy and sound energy when the popcorn pops. When you eat the popcorn, you convert the energy into chemical energy that your body can use to do activities.

Why can you see sunlight in space but can't hear sound?
Sound waves are mechanical and require a medium to travel. Sunlight waves are electromagnetic and do not require a medium to travel. Since there is no medium (no matter) in space, light can travel but sound cannot

Balance the following equation:
___ NH3 + ___ O2 --> ___ N2 + ___ H2O
4, 3, 2, 6
