Discovering Gravitational Energy

One sunny afternoon, Timmy was playing in his backyard. He noticed an apple hanging from a tree branch. Curious, he gave the branch a gentle shake. The apple fell to the ground with a thud. Timmy wondered why the apple fell down and not up.

Timmy's curiosity led him to the school science fair. There, he found a booth about gravitational energy. A friendly teacher explained that gravity is a force that pulls objects towards the Earth. Timmy remembered the apple and realized it was gravity that made it fall. He was excited to learn more about this invisible force.

Back at home, Timmy decided to conduct his own experiment. He filled a balloon with air and let it go. The balloon floated up, and Timmy was puzzled. He learned that the air inside the balloon was lighter than the air outside, so it went up. Timmy understood that gravity works differently depending on the weight of objects.

Timmy was eager to share his new knowledge with his friends. He invited them over for a science day in his backyard. Together, they dropped different objects and watched how gravity worked. Timmy felt proud to teach his friends about gravitational energy. He realized learning could be fun and exciting!
