1. What is Free Fall Speed?

The speed of a falling object is determined by gravity and time, assuming no air resistance. This calculation gives the theoretical terminal speed of an object in free fall.

2. How Does the Calculator Work?

The calculator uses the free fall equation:

Where:

• \( v \) — Speed (m/s)
• \( g \) — Acceleration due to gravity (9.8 m/s² on Earth)
• \( t \) — Time in free fall (seconds)

Explanation: The equation shows that speed increases linearly with time when an object is in free fall under constant gravity.

3. Importance of Speed Calculation

Details: Calculating free fall speed is important in physics, engineering, and safety calculations for falling objects or skydiving.

4. Using the Calculator

Tips: Enter time in seconds and gravity in m/s² (9.8 for Earth). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this account for air resistance?
A: No, this is the theoretical maximum speed without air resistance. Real-world speeds will be lower due to air drag.

Q2: What is terminal velocity with air resistance?
A: Terminal velocity depends on object shape and mass. For humans, it's about 53 m/s (120 mph) in belly-to-earth position.

Q3: Does gravity vary on Earth?
A: Yes, gravity ranges from about 9.78 to 9.83 m/s² depending on location and altitude.

Q4: How accurate is this for short falls?
A: Very accurate for short distances where air resistance is negligible.

Q5: Can I use this for other planets?
A: Yes, just input the appropriate gravity value for that planet (3.7 for Mars, 24.5 for Jupiter, etc.).
