Common JEE Mistakes in Oscillations

Common JEE Mistakes in Oscillations

### Mistake 1

Using SHM equations for large oscillations.

### Correct Concept

Simple pendulum SHM approximation is valid only for:

$$\theta<10^\circ$$

---

### Mistake 2

Assuming amplitude affects time period.

### Correct Relation

$$T\neq f(A)$$

---

### Mistake 3

Confusing angular frequency and frequency.

### Correct Relation

$$\omega=2\pi f$$

---

### Mistake 4

Taking acceleration direction same as displacement.

### Correct Relation

$$a=-\omega^2x$$
