How does the Law of Conservation of Energy explain why a system "loses energy"
Energy can be lost.
Energy can be created and/or destroyed the energy can't be transferred or transformed into another object.
Energy can not be created or destroyed the energy can only be transferred or transformed into another object.
What types of energy are in a Lava Lamp system? Is this energy transforming or transferring?
Thermal to Electrical
Energy transfer
Electrical to Electromagnetic
Energy transformation
Electrical to Mechanical
Energy transformation
Electrical to Electromagnetic
Energy transfer
Which two energies transfer??
Thermal and Kinetic
Kinetic and Potential
Thermal and Potential
Mechanical and Electrical
With arrows what is the path of energy transfer from one object to another?
Hot --> Hotter
Hot --> Cold
Cold --> Hot
Colder --> Cold
Where does most of the energy from the ball go??
It is destroyed from the ball hitting the pins
It is transformed in to energy that knocks down the pins
energy is transferred from the ball to the ground to the pins
It is transferred from the ball to a pin and from one pin to another
What component increases the Kinetic Energy of an object?
Kinetic Energy
0.5
Velocity (speed)
Mass
Kinetic Energy is
energy of movement
stored energy
lost energy
Energy Transfer (is)
can only happen with Kinetic energy and Thermal energy
one energy turning into another energy
the same energy in one object moving to another
can happen with all energies
Energy Transformation (is)
the same energy in one object moving to another
can only happen with Kinetic energy and Thermal energy
one energy turning into another energy
can happen with all energies
Definition of Collision...
Definition of total energy...
the temperature of an object
the total PE an object has
all of the energy in a system
Definition of a system...
Why is particle motion important
the faster a particle moves, the more kinetic energy it has
it proves there is no KE in solids or liquids
it shows that when particles are cold they move more freely
the motion in solid particles is not KE
What does the Law of Conservation of Matter state?
True or False: Energy can be created and destroyed.
Energy can not be created or destroyed just transferred/transformed to another object.
True
Which of these best explains how temperature is related to heat?
Temperature is a measure of the heat of an object.
Heat causes a change in the temperature of an object.
Raising the temperature causes the heat of an object to increase.
Temperature and heat are two different ways to measure the same thing.
During science class, Sophie measures the temperature of the water every minute as it is heating. After a few minutes, the temperature increases to 82ºC. Which other property of the particles increases?
mass
volume
average kinetic energy
average potential
density (denser)
What is convection?
What is radiation?
What is conduction?
Give an example of each.
A diver jumps from a high dive, does a double flip, lands in the water. As she falls she gains KE. This can of energy is balanced by a loss of which form of energy?
thermal energy
internal energy
potential energy
chemical energy
Rosa made a table to organize information about different forms of energy.
What form of energy completes the table?
sound
thermal
electrical
mechanical
How are you doing so far?
Bad
Good
Terrible
Amazing
So-So
(a) energy can be transferred.
Don't use "&", spell "and"
