Imagine a bungee jumper leaping off a bridge or a skydiver jumping out of an airplane. What makes them fall towards the ground? It’s the force of gravity! Gravity is a special force that pulls everything down towards the Earth. We feel gravity every day, whether we’re skiing down a hill, playing a game of tennis, or even when we accidentally drop something.
Gravitational force is an invisible force that pulls two objects towards each other. The strength of this force depends on how much mass an object has. Mass is like the amount of “stuff” inside an object. The more mass something has, the stronger its gravitational pull. For example, the Sun has a lot of mass, so its gravity is strong enough to keep all the planets, including Earth, orbiting around it. Similarly, Earth’s gravity pulls everything, like apples and people, towards its center.
Think about how gravity affects different activities. When you ski down a slope, gravity helps you move faster. When you play tennis, gravity pulls the ball back down after you hit it. But what if there was no gravity? Without gravity, we would float around, and objects wouldn’t fall to the ground. It would be a very strange world!
Did you know that astronauts in space experience very little gravity? That’s why they seem to float inside their spacecraft. This happens because they are in a constant state of free-fall around the Earth, creating the feeling of weightlessness.
Gravity is an amazing force that keeps us grounded and makes life on Earth possible. Next time you drop something or see a ball bounce, remember that gravity is at work!
Gravity Experiment: Gather a few small objects like a feather, a coin, and a small ball. Drop them from the same height and observe which one hits the ground first. Discuss why some objects fall faster than others. Try this experiment with different objects and see if the results change. This will help you understand how gravity works with different masses and shapes.
Gravity in Your World: Take a walk around your home or school and make a list of activities or objects that involve gravity. For example, a swing moving back and forth, a ball rolling down a hill, or leaves falling from a tree. Share your list with a friend or family member and talk about how gravity is involved in each example.
Imagine a World Without Gravity: Draw a picture or write a short story about what life would be like if there was no gravity. How would you move around? What would happen to the objects around you? Use your imagination to think about how different everyday life would be without this important force.

[Music] A bungee jumper leaps from a bridge, and a skydiver jumps from a plane. The force of gravity pulls them towards the ground. Gravity is a force that acts on all objects, pulling them down towards the Earth. We experience the force of gravity in our everyday lives, whether we’re skiing, playing tennis, or accidentally dropping an item.
Gravitational force is an invisible pulling force between two objects. The strength of the gravitational force depends on an object’s mass; the more mass an object has, the greater its gravitational force. The Sun’s gravity pulls the planets around itself, while the Earth’s gravity pulls objects towards its center. An apple is pulled towards the surface of the Earth.
Consider how gravity affects these activities. What would happen if there were no gravity acting on the people and objects?
