1
Q
What is a Quantitative Variable?
A
Data associated with numerical observations
2
Q
What is a Qualitative Variable?
A
Data associated with non-numerical observations
3
Q
Qualitative explanation of Energy conservation in deformation of a metal wire
A
- Wire is stretched, energy must be conserved
- Some energy is stored as elastic strain energy (elastic deformation), some is used to deform wire permanently (plastic deformation)
4
Q
What type of energy can elastic potential energy transform into?
A
- Kinetic
- Gravitational Potential
5
Q
What does a steeper gradient mean?
A
Stiffer material
6
Q
What does a shallower gradient mean?
A
Flexible material
7
