Matter & Energy
This state of matter has a definite shape and volume
What is a solid?
The rate at which an object changes its position
What is velocity?
The energy transferred from one body to another because of a temperature difference.
This causes a gas to expand when heated.
A repeating disturbance that travels through matter or space.
What is a wave?
A material that greatly reduces the flow of electric current
What is an insulator?
Energy stored due to position or configuration.
What is potential energy?
Newton’s Second Law: Force equals mass times this.
What is acceleration?
This causes a gas to expand when heated.
What is thermal expansion?
Light bending when it passes from one medium to another.
What is refraction?
Flow of electrons through a conductor
What is electric current?
Process in which atoms or molecules break free from a liquid and become gas.
What is evaporation?
This law says an object at rest stays at rest unless acted on by a force.
What is Newton’s First Law (Law of Inertia)?
State of matter with no fixed volume but fills its container.
What is gas?
Particles or substances combine to form new substances; this property is studied in chemistry
What is chemical reaction?
This law states that like charges repel and opposites attract.
What is Coulomb’s Law?
Matter being heated until it breaks chemical bonds and changes composition.
What is a chemical reaction?
Time taken to travel a certain distance when speed is constant.
What is time = distance ÷ speed?
Pressure exerted by atmospheric or other gases at high altitudes decreases; this describes this property.
What is atmospheric pressure / decrease in pressure with altitude?
Color, melting point, (etc.) are examples of this kind of property that doesn’t depend on the amount of substance.
What is an intensive property?
A coil that produces a magnetic field when current flows through it.
What is a solenoid (or electromagnet)?
The law which states that energy cannot be created or destroyed, only transformed
What is the law of conservation of energy?
A change in an object momentum
What is Acceleration or deceleration?
The law that relates pressure, volume, and temperature for a fixed amount of gas
What is the Ideal Gas Law?
The property of matter that defines how much mass is in a given volume.
What is density?
Unit of measurement for electrical potential difference.
What is Voltage?
