Mechanical Energy is the energy of ____.
Motion
100
Can electrical energy move well through an insulator?
No.
100
Light energy is the energy we ____
see.
100
Thermal energy is the energy of ____.
Heat
100
Sound energy is the energy we ___.
hear
200
If an object is raised higher in the air, what has increased?
The object's potential energy.
200
Electrical energy is caused by moving _____.
Currents
200
Why do we see things in a mirror?
The light reflects (bounces) back at us.
200
What can you use to measure an objects thermal energy?
A thermometer
200
Sound is caused by ___ of ____ particles.
waves; vibrating
300
PE + KE = ME. What is PE?
Potential Energy
300
A circuit is closed. What does this mean?
That the circuit is complete and the currents of power can flow.
300
What does translucent mean?
The light will travel through the material somewhat, but the image will be blurred or bent.
300
Thermal energy is the energy caused by the ___ of an object moving faster.
Particles.
300
Can you feel the energy created by sound?
Yes, in the form of vibration
400
PE + KE = ME. KE is Kinetic Energy. What is Kinetic Energy? (Your answer must be close)
Kinetic energy is the energy something has by being in motion.
400
Is this circuit complete? Why or why not? A wire is connected from a battery to a light bulb.
No the circuit is not complete because it does not have a wire back to a battery.
400
What does refract mean?
The light bends.
400
As the movement of particles in an object increases, what will happen to the object.
The object's temperature/thermal energy/heat will increase.
400
Can sound travel through objects?
Yes, if the sound makes the object vibrate
500
An object with mechanical energy is experiencing friction. What will happen to the object.
The object will come to a stop (and could heat up).
500
What is a parallel circuit/How is it different from a series circuit?
If a bulb burns out in a parallel circuit, the other bulbs should continue to work.
500
White light hits an object. We see the object as red. Why?
The object absorbs all of the light except red; it reflects red.
500
What happens when an object with a large amount of thermal energy contacts an object with a small amount of thermal energy.
The object with a large amount will transfer some to the other object and their temperatures will begin to balance.
500
Is sound energy a form of kinetic energy?
Yes, the particles are moving.
