Kinetic Energy Explained Simply GCSE Science Video

Struggling with GCSE Physics kinetic energy calculations? 💥 This video brings the formula to life in a way you won't forget! We calculate and compare the kinetic energy (KE) of two very different punches to answer a classic question: Is a heavier, slower punch more powerful than a lighter, faster one?

In this video, you'll see:
🥊 Fighter A (The Heavyweight): Mass = 12 kg, Speed = 5 m/s
🥊 Fighter B (The Speedster): Mass = 7 kg, Speed = 12 m/s

We walk through the kinetic energy formula step-by-step:
KE = ½ x m x v²

Step 1: Square the velocity (v²).

Step 2: Multiply by the mass (m).

Step 3: Multiply by ½ (or divide by 2).

The Result? The faster punch delivers over TRIPLE the energy! This is a perfect demonstration of why velocity is squared in the KE equation—it has a huge impact!
