calculate_kinetic_energy
Compute kinetic energy from mass and velocity components to analyze collisions, vehicle safety, and energy transfer.
Instructions
Calculate kinetic energy from mass and velocity (KE = ½mv²).
Computes the energy of motion for a moving object. Energy is scalar
(direction doesn't matter, only speed). Useful for collision analysis,
vehicle safety, and understanding energy transfer.
Args:
mass: Mass in kilograms (must be positive)
velocity_x: X component of velocity in m/s
velocity_y: Y component of velocity in m/s
velocity_z: Z component of velocity in m/s
Returns:
KineticEnergyResponse containing:
- kinetic_energy: Energy in Joules (J)
- speed: Velocity magnitude in m/s
Tips for LLMs:
- 1 Joule = 1 kg⋅m²/s² = energy to lift 102g by 1m on Earth
- Kinetic energy doubles mass → doubles energy, doubles speed → 4× energy
- Car at highway speed (~30 m/s, 1500 kg) ≈ 675,000 J
- Use to compare impact severity or stopping distances
Example:
# Energy of a 0.145kg baseball at 40 m/s
result = await calculate_kinetic_energy(
mass=0.145,
velocity_x=40.0,
velocity_y=0.0,
velocity_z=0.0
)
