## How to Calculate Gravity: FAQs

### What is the formula for calculating gravity?

Gravity is calculated using the formula F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the separation between their centers.

### Can gravity be negative?

No, gravity is always positive. It is an attractive force, and the negative sign in the formula represents the direction of the force.

### How does altitude affect gravity?

Gravity decreases with increasing altitude. As you move away from the Earth’s center, the gravitational force weakens, leading to a reduction in gravity.

### What is the value of the gravitational constant (G)?

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m^2/kg^2). It plays a crucial role in gravitational calculations.

### Can gravity be felt in space?

While there is no atmosphere in space to transmit sound, astronauts can feel the effects of microgravity. Objects still have mass, and gravitational forces are at play, albeit in a modified form.

### How do gravitational calculations impact space exploration?
