Fs = -kx Spring Force Equation End Slide Spring Force Equation Fs = -kx Spring Force: The force that the spring is putting onto the mass Displacement: The distance that the mass is moved from its equilibrium point along with the direction Spring Constant: The measurement of how stiff the spring is

What does the negative sign mean? Spring Force Equation Fs = -kx What does the negative sign mean?

This vector will always be opposite direction from this vector End Slide Spring Force Equation Fs = -kx This vector will always be opposite direction from this vector

End Slide Spring force of the spring (Fs) is in the negative direction and position (x) is in the positive direction. Spring force of the spring (Fs) is in the positive direction and position (x) is in the negative direction.

Things to know When x = 0m, the spring is neither End Slide Things to know When x = 0m, the spring is neither Suppose Spring A has a higher “k” value than Spring B. Interpret what that means. If you apply the same amount of force on each spring, which will compress more? stretched nor compressed
