  1. 1What is Newton's first law of motion?
    An object at rest stays at rest, and an object in motion stays in motion with constant velocity unless acted upon by a net external force (law of inertia)
  2. 2What is Newton's second law of motion?
    F = ma (Force equals mass times acceleration)
  3. 3What is Newton's third law of motion?
    For every action, there is an equal and opposite reaction
  4. 4What is velocity?
    The rate of change of displacement with respect to time (a vector quantity)
  5. 5What is acceleration?
    The rate of change of velocity with respect to time
  6. 6What is the difference between speed and velocity?
    Speed is a scalar (magnitude only), velocity is a vector (magnitude and direction)
  7. 7What is displacement?
    The change in position of an object (a vector quantity)
  8. 8What is distance?
    The total path length traveled (a scalar quantity)
  9. 9What are the kinematic equations for constant acceleration?
    v = v₀ + at; Δx = v₀t + ½at²; v² = v₀² + 2aΔx; Δx = ½(v + v₀)t
  10. 10What is free fall acceleration on Earth?
    g ≈ 9.8 m/s² (or 10 m/s² for approximations) downward
  11. 11What is projectile motion?
    Motion of an object under the influence of gravity only, with independent horizontal and vertical components
  12. 12What is the horizontal velocity of a projectile?
    Constant throughout the motion (no horizontal acceleration)
  13. 13What is work?
    W = Fd cos θ (Force times displacement times the cosine of the angle between them)
  14. 14What is the unit of work?
    Joule (J) = Newton-meter (N·m)
  15. 15What is kinetic energy?
    KE = ½mv² (energy of motion)
  16. 16What is gravitational potential energy?
    PE = mgh (mass × gravitational acceleration × height)
  17. 17What is the work-energy theorem?
    The net work done on an object equals its change in kinetic energy: W_net = ΔKE
  18. 18What is conservation of mechanical energy?
    In the absence of non-conservative forces, total mechanical energy (KE + PE) remains constant
  19. 19What is power?
    P = W/t or P = Fv (the rate of doing work or transferring energy)
  20. 20What is the unit of power?
    Watt (W) = Joule/second (J/s)
  21. 21What is momentum?
    p = mv (mass times velocity, a vector quantity)
  22. 22What is the conservation of momentum?
    In an isolated system, total momentum before collision equals total momentum after collision
  23. 23What is impulse?
    J = FΔt = Δp (force times time interval equals change in momentum)
  24. 24What is an elastic collision?
    A collision where both momentum and kinetic energy are conserved
  25. 25What is an inelastic collision?
    A collision where momentum is conserved but kinetic energy is not
  26. 26What is a perfectly inelastic collision?
    A collision where objects stick together after impact
  27. 27What is the center of mass?
    The point where the total mass of a system can be considered to be concentrated
  28. 28What is friction?
    A force that opposes relative motion between surfaces in contact
  29. 29What is static friction?
    Friction between surfaces at rest relative to each other (f_s ≤ μ_s N)
  30. 30What is kinetic friction?
    Friction between surfaces in relative motion (f_k = μ_k N)
