Gravity is one of the most important forces in the universe. It is the force that keeps us on the ground, makes apples fall from trees, and keeps the moon in its orbit around the Earth. Here are some interesting gravity facts for kids.
1. Gravity is a force that pulls objects towards each other. The strength of gravity depends on the mass of the objects and the distance between them.
2. The force of gravity is what gives things weight. The weight of an object is equal to its mass multiplied by the acceleration due to gravity.
3. The acceleration due to gravity on the Earth’s surface is 9.8 meters per second squared. This means that a freely falling object will accelerate at a rate of 9.8 meters per second for every second it falls.
4. Gravity is a universal force that works the same way everywhere in the universe. It is the force that holds planets, stars, and galaxies together.
5. The force of gravity is proportional to the masses of the objects involved. This means that the more massive an object is, the stronger its gravitational pull will be.
6. The gravitational force between two objects decreases as the distance between them increases. This is known as the inverse square law.
7. Gravity is what keeps planets in orbit around the sun. The force of gravity between the sun and a planet is what causes the planet to continually fall towards the sun, but the planet’s forward motion keeps it from actually falling into the sun.
8. The force of gravity is what causes tides on Earth. The gravitational pull of the moon and the sun on the Earth’s oceans creates two high tides and two low tides every day.
9. Gravity affects the speed at which time passes. The closer an object is to a massive object, the slower time will pass for that object. This is known as time dilation.
10. The force of gravity is what makes objects fall towards the ground. This is what makes things like bowling balls, apples, and people fall to the ground when they are dropped or jump.
