Unit 3 - Thermal Energy Flashcards
1
Q
Radiant
A
NRG of elecmagnetic waves (light)
2
Q
Kinetic
A
- NRG possessed by obj bc of motion
- 1/2 mv^2
3
Q
Potential
A
NRG stored bc of position/arrangement
4
Q
Elastic Potential
A
NRG when forced out of shape
5
Q
Chem Potential
A
NRG in chem bonds (splitting bonds)
6
Q
Nuclear Potential
A
NRG in nucleus of atom
7
Q
Electrical Potential
A
NRG w/electric charges
8
Q
Thermal
A
- NRG w/movement & interactions of particles in obj
- Total Ek + PE of particles in obj
- Temp is a Ek of particles
- Relies on mass, temp, material
9
Q
Sound
A
NRG in sound waves
10
Q
Work
A
- Force over distance
- W = F(d)
- W = (Fcos)d
11
Q
Positive & Negative work
A
- Force in dir of motion, NRG transferred to obj
- Force opp of motion, NRG from obj
12
Q
Mechanical System
A
Set of obj interacting w/each other
13
Q
Total Mechanical NRG
A
Ek + all Ep
14
Q
Power
A
- Rate work is done
- E/t
15
Q
Kinetic Molecular Theory of Matter
A
Matter are particles in constant motion
