1. Attraction: Gravity is a force of attraction between any two objects with mass. The more mass an object has, the stronger its gravitational pull. This is why we are pulled towards the Earth, and why the Earth is pulled towards the Sun.

2. Acceleration: Gravity causes objects to accelerate towards each other. This means that their speed increases as they get closer. For example, when you drop a ball, it accelerates downwards due to the Earth's gravity. The acceleration due to gravity is approximately 9.8 m/s² on Earth.

3. Orbits: Gravity is the reason planets orbit stars, and moons orbit planets. The object with less mass orbits the object with more mass. The orbiting object is constantly falling towards the larger object, but its forward motion prevents it from crashing into the larger object.

4. Tides: The Moon's gravity pulls on the Earth's oceans, causing the tides. The side of the Earth facing the Moon experiences a high tide, while the opposite side also experiences a high tide.

5. Shape of the Earth: The Earth is not a perfect sphere, but rather an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. This is due to the centrifugal force caused by the Earth's rotation and the gravitational pull of the Sun and Moon.

6. Weight: Gravity determines an object's weight. Weight is the force of gravity acting on an object's mass.

7. Black Holes: Extremely dense objects like black holes have such strong gravity that even light cannot escape their pull.

In summary, the law of gravity affects objects by:

* Attracting them to each other.

* Causing them to accelerate towards each other.

* Creating orbits.

* Influencing tides.

* Affecting the shape of planets.

* Determining an object's weight.

* Forming black holes.

It's important to note that the law of gravity is a fundamental force in the universe, affecting everything from the smallest particles to the largest galaxies.
