Hi, i'm doing gcse physics courswork for ocr twenty first century science the coursework is based around air resistance and terminal velocity my experiment is basically dropping different weights from a 2m height and recording the time it takes for them to fall to the ground. The increase in velocity is accompanied by an increase in air resistance (drag) eventually the air resistance acting upwards on the objects equals the weight acting downwards the overall force on the object is balance or zero it therefore cannot accelerate and continues to fall at constant velocity.
