* Gravity's Constant Pull: The force of gravity pulls on all objects with the same acceleration, regardless of their mass. This acceleration is approximately 9.8 m/s².
* Mass vs. Weight: It's important to distinguish between mass and weight.
* Mass is the amount of matter in an object.
* Weight is the force of gravity acting on an object's mass.
* Newton's Second Law: Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma). While a heavier object has a greater force of gravity acting on it (more weight), it also has more mass, so these factors cancel out, resulting in the same acceleration.
Why Air Resistance Matters:
In reality, air resistance plays a significant role. A feather and a bowling ball will not fall at the same rate in the presence of air because the feather experiences much greater air resistance due to its larger surface area relative to its mass. In a vacuum, however, they would fall at the same rate.
