This calculator helps you determine various parameters related to objects in free fall under gravity.

Free fall is the motion of an object under the influence of gravity only, neglecting air resistance and other forces.

Calculate how long it takes an object to fall from a given height. Uses formula: t = √(2h/g)

m/s²

About Free Fall

Free fall is the motion of an object when gravity is the only force acting upon it. In the absence of air resistance, all objects fall with the same acceleration regardless of their mass.

Basic Free Fall Equations:

For an object falling from rest (v₀ = 0):

v = g × t

h = ½ × g × t²

v² = 2 × g × h

Where:

  • v = final velocity (m/s)
  • g = gravitational acceleration (9.81 m/s² on Earth)
  • t = time of fall (s)
  • h = height or distance fallen (m)
Free Fall with Initial Velocity:

For an object with an initial velocity v₀:

v = v₀ + g × t

h = v₀ × t + ½ × g × t²

v² = v₀² + 2 × g × h

Upward Motion:

For an object initially thrown upward with velocity v₀:

Maximum height: hmax = v₀²/(2g)

Time to reach maximum height: tup = v₀/g

Total time in air: ttotal = 2 × v₀/g

Energy in Free Fall:

Conservation of energy means that potential energy is converted to kinetic energy during free fall:

Potential energy: PE = m × g × h

Kinetic energy: KE = ½ × m × v²

Total energy: PE + KE = constant

Air Resistance Effects:

In real-world situations, air resistance becomes significant, especially at higher velocities:

  • Air resistance force is approximately proportional to the square of velocity: Fair ∝ v²
  • Objects reach a terminal velocity when air resistance equals gravitational force
  • Terminal velocity depends on the object's mass, surface area, shape, and the air density
Gravitational Acceleration on Different Celestial Bodies:
  • Earth: 9.81 m/s²
  • Moon: 1.62 m/s²
  • Mars: 3.71 m/s²
  • Jupiter: 24.79 m/s²
  • Sun: 274 m/s²
Applications of Free Fall:
  • Engineering: Design of drop tests, elevators, and safety equipment
  • Sports: Analysis of diving, jumping, and ball trajectories
  • Space exploration: Orbital mechanics and satellite deployment
  • Construction: Safety considerations for falling objects
  • Physics education: Demonstration of fundamental principles

Understanding Free Fall and Its Concepts

Free fall is a fascinating concept in Physics. It describes the movement of an object that is falling solely under the influence of gravity. This means that no Other forces, like air resistance, are acting on it. When something is in free fall, it accelerates towards the ground at a constant rate. On Earth, that rate is about 9.81 meters per second squared. This calculator helps you explore these principles by allowing you to calculate different aspects related to free fall.

Introducing the Free Fall Calculator
