Term
 Density (ρ)
Definition
 ρ = m/v
Term
 Pressure (3)
Definition
 = force/unit area=ρ(density)gh (depth)  Pressure is the same in every direction in a fluid at at given depth; if it were not, the fluid would flow.
Term
 guage pressure
Definition
 pressure above atmospheric pressureP = PA + PG
Term
 Equation of Continuity
Definition
 ρ1 A1v1=ρ2 A2v2
Term
 Bernoulli's Equation (2)
Definition
 P + 1/2ρv2+ρgy = constanta fluid will flow from high to low pressure causing lift, curve or suction
Term
 Surface Tension (2)
Definition
 Makes water behave elastically (concave/convex); soap lowers ST and allows water to penetrate materials more easily.
Term
 Pendulum period & frequency
Definition
 T = 2Π√(L/g)f = 1/2Π √(g/L)
Term
 Resonance
Definition
 When the frequency from forced vibrations is the same as the natural frequency, the amplitute becomes very large.
