How do you calculate the equivalent spring constant for springs in series?

Use the formula: $\frac{1}{k_{\text {eq, series }}}=\sum_{i} \frac{1}{k_{i}}=\frac{1}{k_{1}}+\frac{1}{k_{2}}+\ldots$

How do you calculate the equivalent spring constant for springs in series?

Use the formula: $\frac{1}{k_{\text {eq, series }}}=\sum_{i} \frac{1}{k_{i}}=\frac{1}{k_{1}}+\frac{1}{k_{2}}+\ldots$

How do you calculate the equivalent spring constant for springs in parallel?

Use the formula: $k_{\text {eq, parallel }}=\sum_{i} k_{i}=k_{1}+k_{2}+\ldots$

What is the first step in solving a problem involving spring forces?

Draw a free-body diagram showing all forces acting on the object, including the spring force.

What is a restoring force?

A force that acts to bring an object back to its equilibrium position.

Define the spring constant (k).

A measure of a spring's stiffness; higher k means a stiffer spring. Measured in N/m.

What is the equilibrium position of a spring?

The spring's natural resting position when no external forces are acting on it; net force is zero.

Define Δx in the context of spring forces.

Δx is the change in the spring's length from its relaxed (equilibrium) length, measured in meters.

What is Hooke's Law?

The relationship between the force exerted by an ideal spring and its change in length: F = -kΔx.

What is the difference between ideal and non-ideal springs?

Ideal springs have negligible mass and perfectly obey Hooke's Law. Non-ideal springs have mass and may not perfectly obey Hooke's Law.

Compare springs in series and springs in parallel regarding their stiffness.

Springs in series are more compliant (less stiff). Springs in parallel are stiffer.

How does displacement relate to force in springs arranged in series versus parallel?

In series, total displacement is the sum of individual displacements. In parallel, the total force is the sum of individual forces.
