Understanding Gravity
* Earth's Gravity: Earth has a gravitational pull, which attracts objects towards it. The strength of this pull depends on the mass of the object and its distance from the center of the Earth.
* Mass of the Object: The more massive an object is, the stronger the gravitational force between it and Earth. This means a heavier object will experience a greater acceleration due to gravity.
Falling Objects and Speed
* Constant Acceleration: All objects, regardless of their mass, fall with the same acceleration due to gravity, which is approximately 9.8 m/s² near the Earth's surface. This means their speed increases by 9.8 meters per second every second they fall.
* Air Resistance: In reality, air resistance plays a significant role. Lighter objects experience greater air resistance, slowing them down. Heavier objects with less surface area per unit mass are less affected by air resistance.
Clarifying Your Question
To provide a more precise answer, please clarify:
* What do you mean by "mass object"? Are you referring to another object in space, or are you looking at the mass of the falling object itself?
* "Speed falling earth" is a bit ambiguous. Are you asking about the effect of another object on Earth's own falling speed (e.g., during a collision with another celestial body)? Or are you asking about the speed of an object falling towards Earth?
Example:
Let's say you have a feather and a bowling ball. Both are dropped from the same height.
* Ideal Scenario (No Air Resistance): They would both fall at the same rate, reaching the ground simultaneously.
* Real World Scenario (With Air Resistance): The feather, with its large surface area, experiences more air resistance and falls much slower than the bowling ball.
Key Points:
* The mass of the falling object determines the force of gravity it experiences, which in turn determines its acceleration.
* Air resistance can significantly affect the speed of a falling object, especially lighter objects with larger surface areas.
* The mass of the Earth is incredibly large, so objects falling towards it experience a significant gravitational pull.
