Ch 5 - Newton's second law of motion Force and acceleration

• Concept development WS 5-2 force and acceleration
• Explaining Free Fall
  • Falling in air
    • air resistance depends on:
      • relative velocity
      • area
      • density of air
    • terminal velocity
      • a case of when F_net = zero
    
    Concept development WS 5-1 Falling and Air resistance
  • sky diving example
  • Concept development WS 5-1 friction

• Force is not Pressure
• Pressure depends on:
  • Amount of force
  • Area of application
  • P = F/A
  • Unit of pressure = Pascal

Activity: Terminal velocity

• Read
• In Ch 5, read 5.4, 5.5, 5.6, 5.7
• Read carefully "Problem Solving" Pg. 62
• Practice questions 1 & 2 pg. 63 Answers on bottom of page
