Final answer:
Explanations of consequences of exceeding terminal velocity, Galileo Galilei's contributions, and gravity's direction in free fall.
Explanation:
Consequences of Exceeding Terminal Velocity:
- Injuries: Exceeding terminal velocity during a fall can lead to severe injuries or fatalities.
- Impact: When terminal velocity is surpassed, the impact force upon landing increases significantly.
Galileo's Contributions:
Galileo Galilei disproved Aristotle's idea of constant velocity falls by demonstrating that all objects fall with the same acceleration due to gravity, regardless of their mass. His experiments with inclined planes helped explain free-fall motion accurately.
Gravity's Direction in Free Fall:
The vector of the acceleration of gravity of any object in free fall points towards the center of the Earth. This means that during free fall, objects accelerate towards the Earth's center due to gravity.
