Why velocity mattersEnergy scales with v²

Current3,500 J

Half the speed875 J

Double the speed14,000 J

Interpretation

Increasing mass increases kinetic energy linearly, while increasing velocity has a squared effect.

FORMULA & STEPSKinetic Energy — Step-by-Step Calculation

3 StepsSequential Calculation Breakdown

1. Start with the formula

Kinetic energy is one-half the mass multiplied by velocity squared.

2. Substitute the values

Velocity squared = 100 m²/s².

3. Calculate

Kinetic energy = 3,500 J.
