  1. Air Resistance And Terminal Velocity

  2. Air Resistance • As objects move through the air, Air Resistance tries to slow them down… Air Resistance Applied Force (Engine)

  3. Air Resistance • As objects accelerate and their speed increases, the amount of drag from the air increases too… Air Resistance Applied Force (Engine)

  4. Air Resistance • A car’s engine can only push so hard, so when it goes fast enough, the air resistance gets so big…the car stops accelerating. Air Resistance Applied Force (Engine)

  5. Air Resistance • The point when the car stops accelerating and Air Resistance = Applied Force is the car’s top speed. (Or top end) Air Resistance Applied Force (Engine)

  6. Air Resistance • The same thing happens when an object is falling down. Air resistance starts out small… Air Resistance Force of gravity

  7. Air Resistance • And increases as the piano picks up speed. Air Resistance Force of gravity

  8. Air Resistance • When air resistance equals the weight of the piano, you have… TERMINAL VELOCITY. Air Resistance Force of gravity

  9. Terminal Velocity • Once an object hits terminal velocity it cannot increase it’s speed any more, velocity is at it’s maximum. • Generally, if an object is heavier, it has a higher terminal velocity.

  10. How it looks on a graph.. Position (x) Time (s)

  11. How it looks on a graph.. The graph is a curve because velocity is increasing. The object is accelerating down… The graph is a straight line because the velocity is constant. Object is at terminal velocity Position (x) The slope of the straight-line part of the graph is the object’s Terminal Velocity Time (s)
