(4.2) - Materials

Question 1

What is a Quantitative Variable?

Answer 1

Data associated with numerical observations

Question 2

What is a Qualitative Variable?

Answer 2

Data associated with non-numerical observations

Question 3

Qualitative explanation of Energy conservation in deformation of a metal wire

Answer 3

• 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)

Question 4

What type of energy can elastic potential energy transform into?

Answer 4

• Kinetic
• Gravitational Potential
