Forms of Energy
Energy caused by the vibrations of matter. You can hear it.
What is sound energy?
This states, "energy can't be created or destroyed. It is only transferred or transformed".
What is the Law of Conservation of Energy?
The stored energy in an object is...
What is Potential energy?
This is the energy an object has due to its motion.
What is kinetic energy?
This form of energy allows walkie talkies to communicate over long distances.
What is electromagnetic energy?
Energy that comes from the movement of atoms within an object. (Even ice has some)
What is thermal energy?
A flashlight is an example of this energy transformation.
What is chemical to light/thermal?
This is the energy stored in a rock on the edge of a cliff.
What is gravitational potential energy?
Car A has mass of 100g, Car B has a mass of 200g. If both cars were driving 55 mph, which would have the greatest kinetic energy? Why?
Car B, it has a greater mass
This equals the total energy in a system? (also called mechanical energy)
What is kinetic energy plus potential energy?
Energy stored in the bonds of molecules. Batteries and food have it in them.
What is chemical energy?
A microwave is an example of this type of energy transformation?
What is electrical to sound/light/mechanical?
or
What is electromagnetic to thermal?
This is the energy stored in a spring that is being compressed.
What is elastic potential energy?
Two identical rocks are rolling down a hill at the same time. Rock A is traveling 10 mph and Rock B is traveling 7 mph. Which rock has more kinetic energy? Why?
Rock A, the speed is higher.
This is what happens to potential and kinetic energy as you fall out of a tree.
What is increasing kinetic energy, decreasing potential energy?
Energy stored in an atom. Released through fission and fusion.
What is nuclear energy?
As a roller coaster goes down a big hill this is the energy transformation taking place?
What is potential energy to kinetic energy?
or
What is mechanical to sound/thermal energy?
This is how I would give an object more potential energy?
What is increase the mass or the height?
These are the two things that affect the kinetic energy of an object.
What is mass and speed?
This is how to affect both the potential and kinetic energy of an object.
What is increase or decrease the mass of the object?
Infrared, ultraviolet, and gamma rays are all examples of this form of energy?
What is electromagnetic energy?
This is the energy transformation that explains how the sun helps us to ride a bike.
What is nuclear to light to chemical to mechanical?
This is the formula for gravitational potential energy.
What is mass times height times gravity?
This is the formula for finding the kinetic energy of an object.
What is 1/2 mass times velocity (speed) squared?
These are all the forms of energy.
What is Mechanical, chemical, sound, thermal, EM, light, nuclear, electrical energy?
