motion forces

• give speed of typical motions

  walking - 1.5 m/s

  running - 3 m/s

  cycling - 6 m/s
• give factors affecting persons motion speed

  age, fitness, distance travelled and fitness
• give gradient of distance time graph

  speed
• give gradient of velocity time graph

  acceleration
• give area of velocity time graph

  distance
• describe process of terminal velocity

  1. object accelerates
  2. create resultant force
  3. resistance increases
  4. zero resultant force
  5. terminal velocity of constant velocity
