What is a Gravity Calculator?

A Gravity Calculator is a specialized physics tool used to compute the force of attraction between masses, weight on different planets, and motion under free fall.

  • ✓ Calculates Weight ($W = mg$) instantly
  • ✓ Solves Free Fall Time & Velocity
  • ✓ Features Multi-Planet Gravity presets
  • ✓ Essential for Physics Students & Engineers
F = G (m1*m2)/r²

What is Free Fall Time (t)?

The FALL t function calculates the exact duration an object takes to hit the ground from a specific height, governed solely by gravitational acceleration.

  • → Input Height (h) in meters
  • → Uses the formula: t = √(2h / g)
  • → Adjusts based on Planet Selection
  • → Critical for physics kinematics and drop tests
t = √(2h / g)

What is Impact Velocity (v)?

The VEL v function determines the final speed an object reaches at the exact moment of impact. It translates potential height into kinetic motion.

  • ⚡ Calculate final speed in m/s or km/h
  • ⚡ Formula used: v = √(2gh)
  • ⚡ Understand Impact Force and energy transfer
  • ⚡ Essential for safety engineering and ballistics
m/s
v = √(2gh)

What is Potential Energy (PE)?

The ENG PE function calculates the energy stored in an object due to its vertical position or height. It measures the work done against gravity.

  • ◈ Result measured in Joules (J)
  • ◈ Formula: PE = m * g * h (Mass × Gravity × Height)
  • ◈ Analyzes energy storage in Mechanical Systems
  • ◈ Used in Hydro-power, Construction, and Rollercoasters
PE = m * g * h

Gravity on Earth

Earth's gravity is the force that keeps our atmosphere in place and our feet on the ground. It is the standard reference point for all gravitational calculations.

  • 🌍 Standard Acceleration: g ≈ 9.81 m/s²
  • 🌍 Varies slightly based on Altitude & Latitude
  • 🌍 The "G-Force" felt at sea level is exactly 1G
  • 🌍 Used as the baseline for Flux Calo presets
g ≈ 9.81 m/s²

Gravitational Acceleration (g)

Acceleration due to gravity is the constant rate at which an object's velocity increases as it falls toward a massive body like Earth.

  • ➜ Constant gain of 9.81 m/s every second
  • ➜ Calculated using g = Δv / Δt
  • ➜ Independent of the object's Mass (Galileo's Principle)
  • ➜ Essential for calculating Force (F=ma)
g = Δv / Δt

Advanced Gravity Terms

Beyond basic weight, gravity involves complex concepts that govern orbital mechanics and deep space travel.

  • ✦ Escape Velocity: The speed needed to break free from a planet's pull.
  • ✦ Inverse Square Law: Gravity weakens rapidly as distance increases.
  • ✦ Center of Gravity: The average location of the weight of an object.
  • ✦ Weightlessness: The sensation of zero-g during free fall or orbit.
vₑ = √(2GM / r)

Mass vs. Weight

One of the most misunderstood concepts in physics. While Mass is the amount of matter in you, Weight is how hard gravity pulls on that matter.

  • ⚖️ Mass (kg): Constant everywhere in the universe.
  • ⚖️ Weight (N): Changes based on the planet's gravity.
  • ⚖️ On the Moon, you weigh only 16.5% of your Earth weight.
  • ⚖️ Your mass remains exactly the same, even in deep space.
W = m × g
MASS IS CONSTANT
