Solution

A free-falling object is any object that is falling under the sole influence of gravity. This means that the only force acting on the object is gravity. In a vacuum, where air resistance is not a factor, all objects fall at the same rate regardless of their mass. This concept is often demonstrated with a feather and a coin. In a vacuum, both would fall at the same rate. However, in the real world, air resistance causes the feather to fall more slowly.

Here are the steps to understand this concept:

  1. Understand the concept of gravity: Gravity is a force that attracts two objects towards each other. On Earth, gravity gives weight to physical objects and causes the ocean tides.

  2. Understand the concept of free fall: Free fall is a type of motion that occurs when the only force acting upon an object is gravity.

  3. Understand the effect of air resistance: In the real world, air resistance can slow down the fall of an object. The amount of air resistance an object experiences depends on its speed, its size, and its shape.

  4. Understand the concept of a vacuum: A vacuum is a space entirely devoid of matter, including air. In a vacuum, all objects fall at the same rate because there is no air resistance to slow them down.

  5. Apply these concepts to a free-falling object: A free-falling object is an object that is falling under the sole influence
