Here's a breakdown:
What is acceleration?
Acceleration is the rate of change of velocity over time. It means how quickly an object's speed or direction is changing.
How does gravity cause acceleration?
Every object with mass exerts a gravitational force on every other object with mass. This force pulls objects towards each other. The stronger the mass of an object, the stronger its gravitational pull.
Gravitational acceleration on Earth:
On Earth, the gravitational acceleration is approximately 9.81 meters per second squared (m/s²). This means that for every second an object falls, its velocity increases by 9.81 meters per second.
Important points:
* Constant: Gravitational acceleration is considered constant near the surface of the Earth. This means it doesn't depend on the mass of the object falling.
* Air resistance: In real-world scenarios, air resistance can affect the acceleration of falling objects.
* Other planets: The gravitational acceleration on other planets is different due to their differing mass and radius.
In summary:
Gravitational acceleration is the acceleration experienced by an object due to gravity. It's a constant value near the surface of the Earth and affects the speed of falling objects.
