### Explanation of Elastic Collision

**Concept Overview:**

In the diagram above, we illustrate an elastic collision scenario where one object is in motion and another object is initially at rest. Elastic collisions are characterized by the conservation of both kinetic energy and momentum.

**Diagram Description:**

- The diagram shows two blocks positioned on a flat surface.
- The block on the left is in motion, heading towards the right with an initial velocity \( v_i \) (indicated by the green arrow).
- The block on the right is at rest and is positioned at a distance \( x_c \) from a fixed barrier or wall.
- The moving block will collide elastically with the stationary block.

**Important Parameters:**

- **Initial Velocity (\( v_i \))**: The velocity of the moving block before collision.
- **Resting Distance (\( x_c \))**: The distance between the resting block and the fixed barrier.
- **Elastic Collision**: In an elastic collision, the total kinetic energy and momentum of the system are conserved.

### Key Points to Remember:

- **Conservation of Momentum**: The total momentum before and after the collision remains the same.
  
  \[
  m_1 \cdot v_{1i} + m_2 \cdot v_{2i} = m_1 \cdot v_{1f} + m_2 \cdot v_{2f}
  \]

- **Conservation of Kinetic Energy**: The total kinetic energy of the system remains constant in an elastic collision.
  
  \[
  \frac{1}{2}m_1 v_{1i}^2 + \frac{1}{2}m_2 v_{2i}^2 = \frac{1}{2}m_1 v_{1f}^2 + \frac{1}{2}m_2 v_{2f}^2
  \]

Where:
- \( m_1 \) and \( m_2 \) are the masses of the blocks.
- \( v_{1i} \) and \( v_{2i} \) are the initial velocities of the blocks.
- \( v_{1f} \) and \( v_{2f} \) are the final velocities of the blocks after the collision.

Understanding elastic collisions is crucial in various applications such as in physics problems, games involving bouncing balls, and understanding particle interactions.
