Term

Definition
Heat transfer due to the actual motion of the fluid itself. 


Term

Definition
The rate of cooling of an objectwhether by conduction, convection, or radiationis approximately proportional to the temperature difference ~ T between the object and its surroundings. 


Term
Conceptual formula for Torque 

Definition
Torque = lever arm X force 


Term
Formula for centripetal force 

Definition


Term
Law of conservation of angular momentum 

Definition
Iw = Iw
Where I = rotational inertia and w = rotational velocity
Angular momentum also = mvr 


Term
How is rotational speed expressed? What Units are used? 

Definition


Term
Distinguish between angular and linear momentum 

Definition
Angular momentum = rotational inertia X rotational velocity
Angular momentum also = mvr
Linear momentum = mass X velocity 


Term
Formula for rotational KE 

Definition


Term

Definition
The line of action of a force F expresses the geometry of how F is applied. It is the line through the point at which F is applied 


Term

Definition
The perpendicular distance between the line of action of a force and a pivot 


Term
connection between linear and rotational motion 

Definition


Term
What are the units for specific heat? 

Definition


Term
What is the equation for heat? 

Definition
Q = m x C x ∆T
m = mass C = specific heat T = temperature 


Term
What is the physicists version of PV = nRT? 

Definition
PV = NKT
N = amount of a substance K = Boltman's constant T = temperature in Kelvins 


Term
What is the formula for average translational kinetic energy? 

Definition
K.E. = 3/2kT
k = Boltman's constant T = temperature in Kelvins 


Term

Definition
motion that carries the molecule from one place to another 


Term

Definition
In addition to the translational kinetic energy of jostling molecules in a substance, there is energy in other forms. There is rotational kinetic energy of molecules and kinetic energy due to internal movements of atoms within molecules. There is also potential energy due to the forces between molecules. So a substance does not contain heatit contains internal energy.
