Classify the following as motion along a straight line, circular oroscillatory motion:
Motion of a child on a see-saw

Options

A. Oscillatory Motion
B. Circular Motion
C. Straight Motion
D. None of the above

Explanation

To classify the motion of a child on a seesaw, we can follow these steps:

### Step 1: Understand the Motion
- A seesaw consists of a long board balanced on a fulcrum (pivot point) in the middle. When one child sits on one end and another child sits on the opposite end, the seesaw tilts up and down.

### Step 2: Observe the Child's Movement
- As one child goes down, the other child goes up. This creates a repetitive motion where the child moves up and down.

### Step 3: Identify the Type of Motion
- The motion of the child on the seesaw is not moving in a straight line, nor is it moving in a circular path. Instead, the child is moving back and forth in a regular pattern.

### Step 4: Classify the Motion
- The up and down movement of the child on the seesaw is classified as **oscillatory motion**. Oscillatory motion refers to any motion that repeats itself in a regular cycle, such as swinging or vibrating.

### Final Classification
- Therefore, the motion of a child on a seesaw is classified as **oscillatory motion**.
