Potential Energy Drop

The Potential Energy Drop Tool ⚡✨ is a simple yet powerful online physics calculator that helps you determine gravitational potential energy (PE) — and how much energy is released when an object falls from a height.

By using the core relationship between mass (m), gravity (g), and height (h), this tool instantly computes the stored energy in elevated objects and the kinetic energy released during a fall.

Ideal for students, engineers, scientists, and educators, it’s your go-to tool for understanding how gravity converts potential energy into motion and impact.

⚙️ Key Features:

• ⚖️ Instant Potential Energy Calculation:
  Enter mass (kg) and height (m) to instantly find the potential energy (Joules) using the formula:

   

  PE = m × g × h

  Where:

  • PE = potential energy (Joules)

  • m = mass (kilograms)

  • g = gravitational acceleration (9.81 m/s² on Earth)

  • h = height (meters)

• 🧮 Reverse Calculation:
  Solve for mass or height when energy and other values are known:

   

  m = PE / (g × h) h = PE / (m × g)

• 🌍 Custom Gravity Mode:
  Calculate potential energy on Earth, Moon, Mars, or custom planets by adjusting gravitational acceleration.

• 💥 Energy Drop Simulation:
  Visualize how stored energy converts to kinetic energy during free fall and how velocity increases with time.

• 🪂 Impact Velocity Calculator:
  Compute final velocity on impact using:

   

  v = √(2gh)

  Ideal for physics labs or impact energy estimation.

• 📏 Supports All Unit Systems:

  • Mass: kg, g, lb, ton

  • Height: m, cm, ft, in

  • Energy: J, kJ, cal, ft·lb

• 🧾 Step-by-Step Breakdown:
  Displays all calculations clearly:

   

  Given: m = 10 kg, h = 5 m   g = 9.81 m/s²   PE = 10 × 9.81 × 5 = 490.5 J Result: 490.5 Joules of potential energy stored. 

• 📊 Energy vs. Height Graph:
  Interactive plot showing how potential energy increases linearly with height.

• 🔋 Mechanical Energy Mode:
  Compare potential and kinetic energy at any point during the fall.

• 📱 Responsive Design:
  Works perfectly across mobile, tablet, and desktop — optimized for classroom and research use.

• 🔒 Privacy Safe:
  100% local processing — no data upload or tracking.

💡 How It Works (Simplified):

The Potential Energy Drop Tool uses the fundamental gravitational potential energy equation to determine how much energy an object stores due to its height:

Formula:

When the object falls, potential energy is converted into kinetic energy, following the law of conservation of energy:

📘 Example Calculations:

Example 1️⃣ – Find Potential Energy

A 5 kg rock is lifted 10 meters above the ground.

✅ Result: 490.5 Joules of potential energy.

Example 2️⃣ – Find Height from Energy

A 1,000 kg car is parked with 147,000 J of potential energy.

✅ Result: The car is 15 meters above the ground.

Example 3️⃣ – Find Impact Velocity

A 2 kg ball falls from a height of 20 m.

✅ Result: The ball hits the ground at ~20 m/s (≈72 km/h).
