Calculator Suite
Kinetic Energy Calculator
Calculate kinetic energy, mass, or velocity using KE = ½mv²
Common Scenarios
Car Kinetic Energy
Energy of a car traveling at highway speed
Bullet Energy
High velocity, low mass example
Cyclist Speed
What speed for a given energy output?
Energy References
The Equation
= Kinetic energy (in Joules or foot-pounds)
= Mass (in kilograms or pounds-mass)
= Velocity (in m/s or ft/s)
Energy Concepts
Energy: The capacity to do work or cause change
Kinetic: Energy due to motion (moving objects)
Conservation: Energy cannot be created or destroyed
Transfer: Kinetic energy can convert to potential energy and vice versa
Velocity-Squared Effect
Kinetic energy scales with the square of velocity:
2× speed = 4× energy
3× speed = 9× energy
This explains why high-speed impacts are so destructive.
Real-World Applications
Vehicle Safety: Crash test energy analysis
Sports: Impact forces in athletics
Engineering: Machine design and energy storage
Ballistics: Projectile impact analysis
Space: Orbital mechanics and spacecraft
