![### Rocket and Gravity: Understanding Distance for Halved Acceleration due to Gravity
In this section, we will learn how to calculate the distance a rocket must be from the center of the Earth in order for the acceleration due to gravity to decrease by half.
#### Force and Acceleration Formulas
Starting with Newton's law of universal gravitation:
\[ F = ma = \frac{GMm}{R^2} \]
Where:
- \(F\) is the gravitational force.
- \(m\) is the mass of the object.
- \(a\) is the acceleration.
- \(G\) is the gravitational constant.
- \(M\) is the mass of the Earth.
- \(R\) is the distance from the center of the Earth.
Next, by isolating the acceleration \(a\), we get:
\[ a = \frac{GM}{R^2} \]
#### Objective
Calculate the distance \( r \) from the center of the Earth where the gravitational acceleration \( a_g \) is half of its usual value at the Earth's surface.
#### Calculating the Distance
We start with the equation where the acceleration due to gravity is halved:
\[ \frac{1}{2} a_g = \frac{GM_{Earth}}{r^2} \]
Knowing that \( a_g \) is approximately \( 9.8 \frac{m}{s^2} \), we can substitute in the formula:
\[ \frac{1}{2} \left( 9.8 \frac{m}{s^2} \right) = \left( 6.67 \times 10^{-11} \frac{N \cdot m^2}{kg^2} \right) \frac{5.98 \times 10^{24} kg}{(r)^2} \]
Solving for \( r \):
\[ r = 9.02 \times 10^6 m \]
Thus, the rocket must be approximately **9.02 million meters** from the center of the Earth for the acceleration due to gravity to be reduced by half.
### Summary
- **Equations used**: Newton's law of gravitation and the formula for acceleration.
- **Gravitational constant \(G\)**: \(6.67 \times 10^{-11} \frac{N \cdot m^2}{kg^2}\).

**Objective:**
Calculate the distance \( r \) the rocket must be from the center of the Earth for the acceleration due to gravity to decrease by half.
**Equations and Constants:**
1. **Newton’s Second Law**:
\[
F = ma
\]
2. **Newton’s Law of Gravitation**:
\[
F = G \frac{M_e m}{r^2}
\]
where:
- \( G \) is the gravitational constant (\( 6.67 \times 10^{-11} \, \text{Nm}^2/\text{kg}^2 \))
- \( M_e \) is the mass of the Earth (\( 5.98 \times 10^{24} \, \text{kg} \))
- \( m \) is the mass of the object (rocket)
- \( r \) is the distance from the center of the Earth
### Step-by-Step Solution:
1. **Given**:
- Initial acceleration due to gravity at the Earth's surface, \( a = 9.8 \, \text{m/s}^2 \)
- Required acceleration due to gravity, \( a' = \frac{1}{2} \times 9.8 \, \text{m/s}^2 = 4.8 \, \text{m/s}^2 \)
2. **Calculation**:
We want to find \( r \) such that the gravitational acceleration is halved.
\[
\frac{1}{2} (9.8 \, \text{m/s}^2) = \left(6.67 \times 10^{-11} \, \frac{\text{Nm}^2}{\text{kg}^2} \right) \left( \frac{5.98 \times 10^{24} \, \text{kg}}{r^2} \right)
