Why Acceleration is the Same
* Gravity's Constant Pull: The force of gravity acts on all objects near Earth's surface with the same acceleration, regardless of their mass. This acceleration is approximately 9.8 m/s².
* 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 = m * a
Where:
* F = Force
* m = Mass
* a = Acceleration
* Free Fall: In free fall, the only force acting on an object is gravity. Since the gravitational acceleration (g) is constant near Earth's surface, the acceleration of any object in free fall is also constant (approximately 9.8 m/s²).
Why Force is Not the Same
* Force Depends on Mass: Although the acceleration due to gravity is constant, the force of gravity acting on each object is directly proportional to its mass. The heavier the object, the stronger the gravitational force.
Example:
Imagine a bowling ball and a feather falling from a high point. They will both accelerate at the same rate (9.8 m/s²) due to gravity. However, the bowling ball experiences a much larger force of gravity because it has a much larger mass.
Key Points:
* Acceleration is Constant: All objects in free fall experience the same acceleration due to gravity.
* Force Varies: The force of gravity acting on an object is directly proportional to its mass, meaning a more massive object experiences a stronger gravitational force.
