Main Body of Lesson
Plenary
- Sketch a velocity-time graph for a falling object. A person jumping out of a plane.
Sheet to do this with diagrams of a person to label forces on at each stage of the jump. This will show when the resultant force is greatest (at the beginning) and when it is balanced ( at terminal velocity both without the chute open and with it open. This also points out that the weight vector does not change but the air resistance vector changes in magnitude according to the speed or if the parachute is open.
