PHYSICS GLOSSARY

2. degree of ------(the number of ways a molecule in the gas phase may move, rotate, or vibrate in space)
4. effect change in apparent frequency of sound when there is relative motion between source and the observer
6. tendency of a force to rotate a body about any axis
9. process takes place at constant pressure
10. heat flow per second per unit area per unit temperature gradient when heat flows normally to an area inside the material
11. the energy is shared equally between the different degrees of freedom and each degree of freedom of a molecule has an average of energy equal to 1/2 kT
12. ratio of tensile stress to the tensile strain if the proportionality limit is not been exceeded

1. square of this is directly proportional to cube of distance between two bodies
3. transfer of energy from one object to another as a result of a difference in temperature
5. first law of -------------- (The change in internal energy of a closed system will be equal to the heat added to the system minus the work done by the system
7. property of an object to resist any rotational motion
8. minimum velocity required by body to overcome planet's gravitational pull to leave the planet and travels into the space
