C.A.: Spring Potential Energy Solve for k
Potential Energy Stored in Springs DEPENDS ON: • CHARACTERISTICS OF SPRING • SPRING CONSTANT (k) • STRETCH PE vs. X PE vs. k
F a stretch (x) Elastic Potential Energy- Springs F / x = constant (k) Hooke’s Law F = kx Slope = k Area = ½ b h Area = ? Area = ½ (Force)(stretch) Area = Work Work = D PE PE spring = ½ (Force)(stretch) PE spring = ½ kx2 PE spring = ½ (F)(x) = ½ (kx)(x)
Potential Energy Stored in Springs PE spring = ½ kx2
C.A. #11: SPRING PE unstretched spring Release mass Measure maximum distance mass falls Vo = 0 = PE s Gained by spring PEg Lost by mass = ½ kx2 mgDh Dh = stretch = x Dh k= 2mg / x
