Physics often requires long calculations, and even a small mistake can lead to the wrong answer. That’s why our Physics Formula Calculator is designed to save time and reduce errors. Just select a formula, enter your values, and get the result in seconds.

🔹 How to Use the Physics Calculator

Using this tool is simple and user-friendly:

1. Choose a formula from the dropdown (Force, Kinetic Energy, Potential Energy, Power, Ohm’s Law).
2. Enter the required values in the input boxes.
3. Click “Calculate” and the result will appear instantly.

👉 Example: If you select Force (F = m × a), enter mass in kilograms and acceleration in m/s². The calculator will instantly give you the force in Newtons.

🔹 Physics Formulas Included in This Calculator

1. Force Formula – Newton’s Second Law

F = m × a

• F = Force (Newtons)
• m = Mass (kg)
• a = Acceleration (m/s²)

This formula is used to calculate how much force is applied to an object when it accelerates.

2. Kinetic Energy Formula

KE = ½ m v²

• KE = Kinetic Energy (Joules)
• m = Mass (kg)
• v = Velocity (m/s)

It measures the energy of an object in motion.

3. Potential Energy Formula

PE = m g h

• PE = Potential Energy (Joules)
• m = Mass (kg)
• g = Gravity (9.8 m/s²)
• h = Height (m)

This formula calculates stored energy based on an object’s position.

4. Power Formula

P = W / t

• P = Power (Watts)
• W = Work (Joules)
• t = Time (seconds)

It tells you how quickly work is done or energy is transferred.

5. Ohm’s Law (Electricity)

V = I × R

• V = Voltage (Volts)
• I = Current (Amperes)
• R = Resistance (Ohms)

This formula is essential for solving circuit problems.
