1
New cards

  • state what all objects reach as they travel through a fluid

  • terminal velocity

2
New cards

  • define terminal velocity

  • the constant velocity an object travelling through a fluid experiences when its drag and its weight become equal

3
New cards

  • state the vector components of an object the instant it begins to fall vertically through a fluid

  • v = 0

  • D = 0

  • a = g

  • F = mg

4
New cards

  • state the vector components of an object falling vertically through a fluid before it reaches terminal velocity

  • v = increasing (at a slower rate)

  • D = increasing

  • a < g → decreasing

    • a = F / m

  • F = mg - D

5
New cards

  • state the vector components of an object falling vertically through a fluid once it reaches terminal velocity

  • v = constant

  • D = mg

  • a = 0

  • F = 0
