Here's the breakdown:
* Gravity: A fundamental force of attraction between any two objects with mass. The more mass an object has, the stronger its gravitational pull.
* Acceleration: A change in velocity over time. It can be a change in speed, a change in direction, or both.
How Gravity Causes Acceleration:
1. Force: Gravity exerts a force on objects, pulling them towards the center of the Earth (or any other massive object).
2. Acceleration: This force causes the object to accelerate. The stronger the force of gravity, the greater the acceleration.
The equation that describes this is:
* F = m * a
Where:
* F is the force of gravity
* m is the mass of the object
* a is the acceleration due to gravity
On Earth, the acceleration due to gravity is approximately 9.8 m/s², meaning that objects falling freely will increase their speed by 9.8 meters per second every second.
Important Note: The acceleration due to gravity is not constant everywhere on Earth. It varies slightly depending on altitude and the density of the Earth's crust below.
