Here's a breakdown:
* Gravity: A fundamental force of attraction between any two objects with mass. The more massive the objects, the stronger the gravitational pull.
* Earth's Gravity: Earth has a large mass, so it exerts a strong gravitational force on objects near its surface. This force is what keeps us grounded, makes objects fall to the ground, and causes the moon to orbit Earth.
Key Concepts:
* Acceleration due to gravity (g): The rate at which objects accelerate towards Earth's surface. It's approximately 9.8 m/s² (meters per second squared).
* Weight: The force of gravity acting on an object's mass. It's measured in Newtons (N).
Formula:
The force of gravity (weight) can be calculated using the following formula:
* Weight (W) = mass (m) x acceleration due to gravity (g)
