## Springs in Series

### Formula

$$\frac{1}{k_{eq}}=\frac{1}{k_1}+\frac{1}{k_2}+...$$

### For Two Springs

$$k_{eq}=\frac{k_1k_2}{k_1+k_2}$$

### Conditions

Equivalent spring constant decreases.

---

## Springs in Parallel

### Formula

$$k_{eq}=k_1+k_2+...$$

### Conditions

Equivalent spring constant increases.

### Usage

- Used in spring combination problems.
