⚡ Kinetic Energy Calculator
Calculate kinetic energy using mass and velocity – simple, fast & student-friendly 🚀
📘 Kinetic Energy Formula
KE = 1/2 × m × v2
Where:
• KE = Kinetic Energy (Joules, J)
• m = Mass (kg)
• v = Velocity (m/s)
🧠 Example (Step-by-Step)
If mass = 10 kg
Velocity = 5 m/s
KE = 1/2 × 10 × (5)2
KE = 0.5 × 10 × 25
KE = 125 Joules (J)

🧠 FAQs- Kinetic Energy Calculator
❓ What is kinetic energy in simple words?
👉 Kinetic energy is the energy possessed by an object due to its motion. Any moving object has kinetic energy.
❓ What is the SI unit of kinetic energy?
👉 The SI unit of kinetic energy is the Joule (J).
❓ What happens to kinetic energy if velocity doubles?
👉 If velocity doubles, kinetic energy increases four times, because KE ∝ v².
❓ Can kinetic energy be zero?
👉 Yes. If an object is at rest (velocity = 0), its kinetic energy is zero.
❓ Is this calculator useful for JEE & NEET exams?
👉 Absolutely ✅. It is ideal for concept verification, numerical practice, and quick checking.
