As the rock falls, the magnitude of the acceleration remains constant and equal to the acceleration due to gravity, which is approximately 9.8 m/s². This means that the rock is accelerating at a constant rate downwards.
The speed of the rock, on the other hand, continuously increases as it falls. This is because the rock is accelerating due to the force of gravity pulling it downwards. As time goes on, the rock's speed increases as the acceleration remains constant, causing it to fall faster and faster.
7) A rock is dropped from a bridge. What happens to the magni tude of the acceleration and the speed of the rock as it falls? (neglect friction]
