Relativistic Mass

• What did Einstein propose in his 1905 paper?

  Mass can be converted into energy
• What is the equation for mass-energy equivalence?

  E = mc²
• What does E represent in the equation E = mc²?

  Energy measured in joules (J)
• What does m represent in the equation E = mc²?

  Mass measured in kilograms (kg)
• What does c represent in the equation E = mc²?

  The speed of light measured in m/s
• What are scenarios where mass is converted to energy or energy to mass?

  • Fusion of hydrogen into helium in the Sun
  • Fission of uranium in nuclear power plants
  • Nuclear weapons
  • High-energy particle collisions in accelerators
• What is an object's proper mass also called?

  Rest mass
• How is the mass of an object measured by an observer in motion described?

  Relativistic mass
• What is the formula for relativistic mass?

  m = m₀ / √(1 - v²/c²)
• What happens to an object's mass as its speed approaches the speed of light?

  Its mass increases towards infinity

  
• What is the relationship between speed and relativistic mass?

  • Mass increases as speed approaches c
  • At speeds near c, mass tends towards infinity

  
• What is the rest energy of a stationary object?

  E = m₀c²
• How do you calculate the total energy of a particle at maximum speed?


  E = γm₀c²

  Rest energy

  • Look for significant speeds close to c
  • Consider relativistic effects
  • Context clues may indicate necessary equations
