2. 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

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

4. 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

5. 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.

6. 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
