Direct and Inverse Proportion
The Stretch is Proportional to the Force
• The greater the force, the greater
the stretch
• Force ~ Stretch
• F ~ x
• F = k∙x
• x2/x1 = F2/F1
• x2 is to x1 as F2 is to F1
In a Gas
Pressure and Volume are
Inversely Related
• When the volume goes
down, the pressure goes up
• Pressure is inversely
proportional to volume
• P ~ 1/V
Direct: F1/F2 = x1/x2
• P=k/V
Inverse: P1/P2 = V2/V1
• P1V1 = P2V2
Ratios are upside down
For Inverse Proportion
• Direct Proportion
F1 / F2 =
• Inverse Proportion
P1 / P2 = V2 / V1
• Inverse Square
•
F1 / F2 = ( r2 /r1 )2
a1 / a2 = ( r2 /r1 )2
x1 / x2
