1. What is Gravitational Force?

Gravitational force is the attractive force between two masses. On Earth, it's the force that gives weight to physical objects and causes them to fall toward the ground when dropped.

2. How Does the Calculator Work?

The calculator uses the gravitational force equation:

Where:

• \( F \) — Gravitational force (N)
• \( m \) — Mass of the object (kg)
• \( g \) — Acceleration due to gravity (m/s²)

Explanation: The standard value for Earth's gravity is 9.81 m/s², but it varies slightly depending on location (latitude, altitude).

3. Importance of Gravitational Force Calculation

Details: Understanding gravitational force is essential in physics, engineering, and many practical applications like construction, aerospace, and mechanical design.

4. Using the Calculator

Tips: Enter mass in kilograms and gravity in m/s² (default is Earth's gravity 9.81 m/s²). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard value of Earth's gravity?
A: The standard value is 9.80665 m/s², but 9.81 m/s² is commonly used for calculations.

Q2: Does gravity change with location?
A: Yes, gravity is slightly stronger at the poles than at the equator and decreases with altitude.

Q3: How is this different from Newton's Law of Universal Gravitation?
A: This is a simplified version for objects near Earth's surface. The universal law includes both masses and the distance between them.

Q4: What is the relationship between weight and mass?
A: Weight is the gravitational force acting on a mass. Weight = mass × gravity.

Q5: How would this calculation differ on other planets?
A: You would use the surface gravity of that planet instead of Earth's gravity.
