**Note:**You will get the**main formulas**. You need to be able to manipulate them (I will not write down the triangle on the board). Come prepared with a**pen**and**scientific calculator**.## Study Guide

4.2

- Define with an example: work, energy, heat, kinetic-molecular theory, kinetic energy, thermal energy, heat capacity, temperature, first and second law of thermodynamics
- Calculate work (understand the formula, know units, be able to manipulate the formula)

5.1 Analyzing and Measuring Motion

- define with an example: scalar vs. vector quantities, distance vs. displacement, speed vs. velocity, acceleration
- calculate displacement , distance, speed, velocity and acceleration

5.2 Energy of Motion

- calculate kinetic energy

5.3 Potential Energy

- explain the difference between elastic potential, chemical potential, nuclear potential, and gravitational potential energy
- calculate gravitational potential energy

6.1 Efficiency of Energy Conversion

- define efficiency (differentiate between useful and waste energy)
- calculate efficiency
