Key Formulas
Work:
W = F × d (Force × Distance)
Power:
P = W / t (Work / Time)
Kinetic Energy:
KE = ½mv² (Half × Mass × Velocity²)
Potential Energy:
PE = mgh (Mass × Gravity × Height)

About Work and Energy Calculator
Calculate Work, Power, and Energy
This calculator helps you compute work done, power output, and kinetic energy using fundamental physics formulas. These concepts are essential for understanding energy transfer and mechanical systems.
Features
- Calculate work from force and distance
- Calculate power from work and time
- Calculate kinetic energy from mass and velocity
- Multiple unit conversions
- Real-world examples
- Formula explanations
- High precision results
Understanding the Concepts
Work: Energy transferred when a force moves an object. Only the component of force in the direction of motion does work.
Power: The rate at which work is done or energy is transferred. A more powerful engine does the same work in less time.
Energy: The capacity to do work. Kinetic energy is the energy of motion, while potential energy is stored energy.
Applications
- Mechanical engineering design
- Vehicle performance analysis
- Energy efficiency calculations
- Sports physics and biomechanics
- Electrical power systems
- Renewable energy systems
Important Notes
- Work is only done when force causes displacement
- Energy is conserved in isolated systems
- Power = Force × Velocity (alternative formula)
- 1 Watt = 1 Joule per second
- 1 horsepower ≈ 746 Watts
