* Gravity: Every object with mass exerts a force of attraction on every other object with mass. This force is called gravity. The Earth has a very large mass, so it exerts a strong gravitational pull on objects near its surface.
* Force and Acceleration: 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.
* Falling Objects: When an object falls, the Earth's gravity is the net force acting on it. This force causes the object to accelerate downwards.
* Constant Acceleration: The acceleration due to gravity near the Earth's surface is almost constant, approximately 9.8 m/s². This means that for every second the object falls, its downward velocity increases by 9.8 meters per second.
In short: The Earth's gravitational pull exerts a force on falling objects, causing them to accelerate downwards at a constant rate.
