## Physics Equations Explained

### Gravitational Force

1. **Equation:** 
\[ F_g = G \frac{m_1 m_2}{r^2} \]
   - **Description:** This is the formula for the gravitational force between two masses, \(m_1\) and \(m_2\), separated by a distance \(r\). 
   - **Variables:**
     - \( G \): Gravitational constant
     - \( m_1 \): Mass of the first object
     - \( m_2 \): Mass of the second object
     - \( r \): Distance between the centers of the two masses

### Potential and Kinetic Energy

2. **Equation:**
\[ mgh = \frac{1}{2} mv^2 \]
   - **Description:** This equation illustrates the conversion of potential energy (mgh) to kinetic energy (\(\frac{1}{2} mv^2\)).
   - **Variables:**
     - \( m \): Mass of the object
     - \( g \): Acceleration due to gravity
     - \( h \): Height
     - \( v \): Velocity

### Kinematic Equation for Position

3. **Equation:**
\[ x = x_0 + v_0 t + \frac{1}{2} at^2 \]
   - **Description:** This is the kinematic equation for the position of an object under constant acceleration.
   - **Variables:**
     - \( x \): Final position
     - \( x_0 \): Initial position
     - \( v_0 \): Initial velocity
     - \( t \): Time
     - \( a \): Acceleration
