Term
Define equilibrium conceptually and mathetmatically 

Definition
A system with no translational or angular acceleration (it is moving and rotating at constant velocity) F upward = F downward F leftward = F rightward 


Term
Explain the difference between static and dynamic equilibrium 

Definition
Static Equilibrium  when all translational and angular velocities are constant and zero
Dynamic Equilibrium  when all translational and angular velocities are constant and nonzero 


Term
What are the three useful equations for Torque problems? 

Definition
Torque = Frsinθ
Torque = Fl
Torque_{clockwise }= Torque_{counterclockwise} 


Term

Definition

Definition


Term
What is the formula for gravitational potential energy? 

Definition


Term
What is the formula for elastic potential energy? 

Definition


Term
What are the three formulas for Work and when do they apply? 

Definition
W = Fdcosθ (for all forces except friction)
W = ΔK + ΔU + ΔE (no heat)
W = ΔK + ΔU (no friction, no heat) 


Term
Explain the difference between conservative and nonconservative forces 

Definition
The work done against conservative forces is conserved in potential energy; the work done against nonconservative forces is not conserved 


Term
Give four examples of conservative forces 

Definition
Gravitational forces, Hooke's law forces, electrical and magnetic field forces 


Term

Definition
The rate of energy transfer 


Term
What are the three formulas for Power? 

Definition
P = ΔE / t
P = W/t
P = FvcosΘ
