Standard Gravity Value:
| From: | To: |
The acceleration due to gravity (g) is the acceleration experienced by objects due to Earth's gravitational pull. The standard value is approximately 9.81 m/s², though it varies slightly depending on location and altitude.
The calculator uses the standard gravity formula:
Where:
Explanation: This formula calculates the gravitational force acting on an object with a given mass at Earth's surface.
Details: Understanding gravitational forces is essential in physics, engineering, and everyday applications. It helps determine weight, design structures, and calculate forces in mechanical systems.
Tips: Enter mass in kilograms. The calculator will compute the corresponding weight force using the standard gravity value of 9.81 m/s².
Q1: Why is g = 9.81 m/s²?
A: This is the average acceleration due to gravity at Earth's surface, calculated from gravitational constant and Earth's mass and radius.
Q2: Does gravity change with location?
A: Yes, gravity varies slightly with latitude, altitude, and local geological features, typically ranging from 9.76 to 9.83 m/s².
Q3: How is gravity different on other planets?
A: Other celestial bodies have different gravitational accelerations based on their mass and radius. For example, Mars has about 3.71 m/s² gravity.
Q4: What's the difference between mass and weight?
A: Mass is the amount of matter (constant everywhere), while weight is the force of gravity acting on that mass (varies with gravity).
Q5: How was the value of g determined?
A: Through precise measurements using pendulums, free-fall experiments, and modern gravimeters over centuries of scientific study.
