Question

complete the following statements about free - fall acceleration. free fall is the motion of an object when galileo discovered that, neglecting the effect of air, all objects in free fall galileos results were verified near earths surface, free - fall acceleration is

Explanation:

Free - fall is when only gravity acts on an object. Galileo found all objects in free - fall have the same acceleration. His results were verified by Apollo 15's feather - hammer experiment. Near Earth's surface, free - fall acceleration is approximately 9.8 m/s².

Answer:

• Free fall is the motion of an object when the only force acting on it is gravity.
• Galileo discovered that, neglecting the effect of air, all objects in free fall have the same acceleration.
• Galileo's results were verified by the Apollo 15 feather - hammer experiment on the Moon.
• Near Earth's surface, free - fall acceleration is approximately 9.8 m/s².
