FAQs on Momentum Calculator

  1. What is momentum?
    • Momentum is the product of an object’s mass and its velocity, representing its motion.
  2. How do I use the Momentum Calculator?
    • Enter the mass and velocity to calculate the momentum.
  3. Is momentum conserved in all collisions?
    • Yes, in closed systems, momentum remains constant.
  4. Can momentum be negative?
    • Yes, momentum can be negative if the velocity is in the opposite direction.
  5. Why doesn’t it account for friction or air resistance?
    • To simplify calculations; these factors can be added separately.
  6. Is momentum relevant in everyday life?
    • Yes, it’s crucial in sports, vehicle safety, and more.
  7. What’s the difference between elastic and inelastic collisions?
    • In elastic collisions, kinetic energy is conserved; in inelastic, it’s not.
  8. Can I use this for analyzing car crashes?
    • Yes, it can estimate collision forces.
  9. Is momentum the same as inertia?
    • No, inertia is an object’s resistance to change in motion; momentum is its motion itself.
  10. Can I calculate momentum for celestial bodies like planets?
    • Yes, it’s used in celestial mechanics to analyze planetary motion.
