100
Energy of motion
What is kinetic energy
100
Explain the transformation that takes place when you rub your hands together. (3 steps)
What is potential energy to kinetic energy to thermal energy
100
As the mass of an object moving at a given speed decreases its kinetic energy will
What is decrease
100
Sedimentary rocks are made of these
What are sediments
100
Igneous, Metamorphic, and Sedimentary
What are the three kinds of rocks
200
Energy that is stored in an object
What is potential energy?
200
When you drop a book on the floor, what happens to its original potential energy?
What is the potential energy turns into kinetic and thermal energy
200
As the speed of a falling object increases, its potential energy will
What is decrease
200
Another name for molten rock
What is magma
200
Igneous rocks can be found in or around this landform
What is a volcano
300
Energy that is stored in bonds of molecules
What is chemical energy
300
Explain the transformation that takes place when you turn on a flashlight. From the battery to the light. 4 steps
What is Chemical (of the battery) to electrical (flow of elctrons) to radient (of the light) to thermal ( the heat produced by the light)
300
How does potential energy become kinetic energy?
What is when an outside force acts upon an object with potential energy, that force turns the potential energy into kinetic energy.
300
This is energy from the sun
What is radiant energy
300
These two things are required for metamorphic rock to form
What are heat and pressure
400
Energy in the form of heat
What is thermal energy
400
Explain the transformation of a book falling from a table. Explain the type of energy and where it comes from. 3 steps
What is potential (the book resting on the table) to kinetic (the book falling) to thermal (the friction between the book and the air)
400
A basketball is dropped from a height of 2m and another identical basketball is dropped from a height of 4m. Which ball has more kinetic energy just before it hits the ground?
What is The basketball dropped from a height of 4m because it has more speed.
400
State the Law of Conservation of Energy
What is Energy can not be created of destroyed it can only be transferred or transformed.
400
A rock that was sediment, then went under pressure, then was melted down and crystalized or cooled inside a volcano is this type of rock.
What is igneous rock
500
Energy from potential and kinetic energy working together in a system
What is mechanical energy
500
When an archer pulls back an arrow and then lets it go, what forms of energy are being used (4 forms)
What is potential (when the arrow is pulled back), kinetic (when the archer lets it go), mechanical and thermal (when the arrow is moving through the air)
500
When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. Explain how the law of conservation of energy is obeyed.
What is During each bounce, some of the kinetic energy of the ball in transfered into thermal energy. As a result, energy is not created or destroyed, but only changes form so that the law of conservation of energy is obeyed.
500
Name Each type of energy and give an example.
What are Kinetic, Potential, Light, Heat, Chemical, Nuclear, and electrical
500
Explain how the rock cycle is like recycling
What is one type of rock is used reused to create a different type of rock
