This is an example of radiant energy being changed to chemical energy.
What is photosynthesis?
100
What are the units for Power?
Watts
100
This type of energy is produced by the vibrations of matter. These vibrations can move through solid, liquid or gaseous matter, but they cannot travel through empty space.
What is sound energy?
200
A force (a push or pull) applied to an object which forces the object to move.
What is work?
200
Energy an object has due to its position or condition.
What is potential energy?
200
This is an example of chemical energy being changed to light energy.
What is a fire?
200
What is Power? Give the conceptual definition (words, not an equation)
Power is how quickly work is done
200
Sound waves travel as v____________s.
Vibrations
300
The energy any object has because of its motion.
What is kinetic energy?
300
Energy formed when an atom splits apart or when two atoms join to form one. (trivia)
What is nuclear energy?
300
This is an example of electrical energy being changed to radiant (light) energy.
What is a lamp?
300
A dog runs using 60 Joules in 12 seconds. How powerful is he?
5 Watts
300
Sound energy has the unique ability to bounce off of walls, or reverberate. This is what it is called when sound energy bounces off of a surface and returns. (trivia question)
What is an echo?
400
Stored energy or energy that an object has due to its position.
What is potential energy?
400
Energy stored in the way atoms are connected to each other.
What is chemical energy?
400
This is an example of light energy being changed to electrical energy.
What are solar panels?
400
A mule helps lifts a 7 Newton weight 20 meters in 2 seconds. What power does the mule use?
70 Watts
400
These animals use low frequency sounds to communicate over long distances. (trivia question)
What are elephants?
500
As a roller coaster car goes down a hill, its potential energy is changed into this.
What is kinetic energy?
500
Energy of the movement of atoms and molecules.
What is thermal energy?
500
Name the energy transformations that occur while driving a car.
Chemical + Thermal --> Kinetic
500
True or false:
1 Watt = kg m^2 /s^3
true
500
Sound and Light waves are both longitudinal (waves that travel up and down & side to side)
True or False?
