Gravity experiment: Which will land first, free fall feathers or iron balls? - Customized science museum exhibitions, campus community science popularization equipment, science exhibition source manufacturer exhibition description and scientific principle introduction:
An object that falls without any resistance and only under the action of gravity is called a "free fall". An object that begins to fall from a stationary state under the influence of Earth's gravity. The airspace near the Earth's surface can be regarded as a steady gravity field, and if atmospheric resistance is not considered, free fall motion in this area is uniformly accelerated linear motion. The motion of a regular object with zero initial velocity under the action of gravity is called free fall motion. Free fall motion is an ideal logistics model. The speed of free fall is independent of the mass of the object, so in a vacuum state, feathers and iron balls fall at the same speed.
