- Scalars and Vectors
Scalars and Vectors (1) Scalar – physical quantity that is specified in terms of a single real number, or magnitude Ex Length, temperature, mass, speed Vector – physical quantity that is specified by both magnitude and direction Ex Force, velocity, displacement, acceleration We represent vectors graphically or quantitatively: Graphically: through arrows with the orientation representing

V1 is the volume at the intersection of an isothermal path from state 2 and an adiabatic path from state 3 If your task is to calculate the entropy change for an isochoric path, you must find V1 at the intersection of an isothermal path from state 2 and an adiabatic path from state 3

v0 = *a0; if (v0 < 0) v0 = -v0; v1 = v0 + v0; Sometimes it’s easier to invert the original condition In this case, we changed “continue if v0 < 0” to “skip if v0 >= 0”

Kinetics of rigid bodies in plane motion – Work and Energy Principle of Work and Energy for a Rigid Body Our basic principle still applies: T1 + U12 = T2 where T1 = total kinetic energy in position 1 U12 = total external work done from position 1 to position 2 T2 = total kinetic energy in position 2 Recall: A system of forces can be reduced to a resultant force and a resultant moment at some
