  1. Uniform Acceleration

  2. Galileo Galilei (1564-1642)

  3. Galileo Galilei • ≈ 1590 he began a book, De motu ("On motion"). • He examined motion of objects rolling down inclined planes, slowly falling. The effect of gravity, diluted.

  5. Pg. 53 Sample Problem s = 42 s = 0 ∆t = 5.5 s Substitute Solve: ∆x = ? • Vi= 42 • Vf = 0 • ∆t = 5.5 s • ∆x = ? • ∆x = (Vi + Vf) ∆t Given: Unknown: Equation:

  6. a = 4.8 s = 0 Pg. 55 Sample Problem t = 15 s Equation: ∆x = (Vf) ∆t Vf = a(∆t) Substitute Solve: ∆x = ? s = ? • Vi= 42 • a = 4.8 • ∆t = 5.5 s • Vf = ? • ∆x = ? Given: Unknown:

  7. s = 4.30 • a = 3.0 Pg. 55 Practice Problem 2 t = 5.0 s ∆x = (Vf) ∆t Equation: Vf = a(∆t) s = ? Substitute Solve: ∆x = ? • Vi= 42 • a = 3.0 • ∆t = 5.5 s • Vf = ? • ∆x = ? Given: Unknown:
