### Quiz 1

v = initial velocity + (acceleration)(time)
x = initial position + (initial velocity)(time) + 1/2(acceleration)(time)^2
v^2 = (initial velocity)^2 + 2(acceleration)(Δx)
Acceleration of Centripetal force = velocity^2/radius
Newton's First Law An object at rest will stay at rest unless an external force is applied to it.
Newton's Second Law Σ Forces = mass*acceleration
Newton's Third Law For every action there is an equal and opposite reaction.
Potential Gravitational Energy U = mass*gravity*height
Potential Spring Energy U = 1/2(spring constant)(Δx)^2
Work = force*Δx*cosθ
Average Power = work/Δtime
Power = force*velocity*cosθ
Archimede's Principle ρ/(ρ fluid) = weight/(weight of fluid displaced)
Pascal's principle P = ρgh
Bernoulli's equation P1 + ρgh + 1/2ρv^2 = P2 + ρgh + 1/2ρv^2
