1-Dimensional Vertical Motion

1-Dimensional Vertical Motion. Free Fall - an object dropped from the surface of a planet in the absence of air resistance undergoes “free fall” Acceleration due to the force of gravity, on earth, is known as, “g”. g = -9.8 m/s/s

Presentation Transcript

  1. 1-Dimensional Vertical Motion Free Fall - an object dropped from the surface of a planet in the absence of air resistance undergoes “free fall” Acceleration due to the force of gravity, on earth, is known as, “g”. g = -9.8 m/s/s All objects, on earth, accelerate at the constant rate of -9.8 m/s/s, in the absence of air resistance.

  2. Air resistance - the force exerted by the air on a falling object

  3. Terminal Velocity - the largest velocity that is reached by a falling object when air resistance balances the pull of gravity the object stops accelerating and speed remains constant = TERMINAL SPEED.
