Matter
Does not have a definite shape nor definite volume.
Solid, Liquid, or Gas?
What is gas.
The outermost layer of the Earth
What is the crust
The part of an atom with a positive charge
What is a proton
Use F=ma
A car with a mass of 5 drives with an acceleration of 3. What is the force?
What is 15
This is the stored energy in an object(Ex. A ball about to be dropped, a rollercoaster at the top of a hill)
What is potential energy.
Has a definite shape and volume
Solid, Liquid, or Gas
What is solid.
The innermost layer of the Earth
What is the inner core
The part of an atom with a negative charge
What are electrons
Use F=ma
A car with a mass of 100 drives with an acceleration of 2.5 . What is the force?
What is 250
This is the energy when something is moving (a car driving, a person running)
What is kinetic energy.
The process where water changes to a gas (Ex. water--> vapor)
What is evaporation
The thickest layer of the Earth
What is the mantle
A neutral atom has the same amount of __________ and ________________
What are protons and electrons
Use PE=mgh, g=9.8
A ball with a mass of 10 is dropped from a height of 10. What is the potential energy before it falls?
What is 98
This number is the acceleration due to gravity if you drop an object anywhere on Earth.
What is 9.8 m/s
The unit for mass
What is kilogram.
This layer of the Earth is very hot but still a solid
What is the inner core
This group of elements in dull (not shiny), poor conductivity, and very brittle.
What are nonmetals
Use KE=.5mv^2
A ball with a mass of 10 is dropped and falls with a speed of 100. What is the kinetic energy as it falls?
What is 9800
This is the force that slows something down on a rough surface
What is friction
The process of gas turning into a liquid (Ex.Vapor--> Water)
Condensation
This is the reason why the inner core is solid even though it is very warm
What is pressure/the weight of the Earth around it
The atomic number can give you the number of __________ or _______________
Protons or Electrons
Use V=Frequency x Wavelength
A wave travels with a speed of 20 and a frequency of 2. What is its wavelength?
What is 10
This is the formula we use to calculate force.
What is F=ma
