TodayGalileo - from Projectiles to Principles

• Motion of bodies with constant acceleration a

• Freely Falling Bodies:

  • a = 9.8 m/s2 in vertical direction
  • We can approximate as a = 10 m/s2

• Projectiles - Motion in 2 dimension

  • Demonstrations

• Galileo’s principles –

  • Principle of inertia
  • Principle of superposition

• Foundations for Newton’s laws
