Consider a model rocket launched skyward as shown below. Shade in the boxes to indicate how the forces of thrust, drag and gravity change along the rocket's flight path..

pdf worksheet.




See the video of the dynamic model rocket launch.
From launch to Point A fuel is burning producing thrust. Where at point A the fuel is spent and thrust is reduced to zero.
From point A to point B the rocket coasts to maximum height.
From Point B to point C the rocket free falls.
At point C the parachute is ejected.
From point C to touch down the rocket descends, at constant speed, with its parachute fully deployed.

1. What stage/s of the flight path are/is impacted by unbalanced forces?

2. What stage/s of the flight path are/is impacted by balanced forces?

3. What force/s are/is acting on the rocket as it remains on the ground after descending with its parachute?

4. What force is significantly changed when the parachute is deployed?
