Answer:
1) Acceleration due to gravity is produced on a freely falling body. Due to this, when a man jumps from a significant height, he will have enough time to attain maximum velocity before he reaches the ground. Due to this, the man will have high kinetic energy and strikes the ground with great force. Therefore, there is more probability of getting hurt when a man jumps from a significant height.
2) The falling of an object in the absence of any external resistance with acceleration due to gravity is called a free fall.
