Detailed explanation-1: -Objects tend to fall downward towards the earth as the earth pulls the objects due to its gravity. The pull is known as gravitational force.

Detailed explanation-2: -Gravity is the force that pulls all objects in the universe toward each other. On Earth, gravity pulls all objects “downward” toward the center of the planet.

Detailed explanation-3: -The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity.

Detailed explanation-4: -On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second.
