1. Objects that fall under the influence of gravity and are heavy enough to neglect air resistance.

2. v t

3. d t

6. Position vs timeVelocity vs time

7. Moon g = 1.6 m/s 2 The first second The ball has fallen.8 m and at 1.6 m/s 2 After three seconds the ball has fallen 7.2m and is moving at a speed of 4.8 m/s Earth g = 9.8 m/s 2 The first second The ball has fallen 4.9 m And is moving 9.8 m/s After three seconds The ball has fallen 44.1m and is moving at 29.4m/ s

8. A. What is its final velocity? B. How far has it fallen?

9. A. What is the maximum height reached by the object? B. How long does it take for the object to reach its maximum height? C. How long does it take for the object to return to where it was thrown? D. What is the object’s speed after 2.0 seconds?

11. Acceleration decreases to zero Velocity reaches a constant velocity called Terminal velocity. Video 1 Video Video 2 Video 2
