Do You Know about Gravity? Find out How Gravity Works — from an Outer Space Perspective

You Know Gravity teaches you everything you need to know about gravity -- especially from an outer space perspective.

A few months ago, I reviewed a science app for kids called Meet Science: Force and Motion. The app, in the form of a textbook combined with interactive experiments, tries to teach kids the concepts of motion and force. Gravity is one of the topics touched in the app, but it’s definitely not the main topic.

My app pick for today is a special app that wants to address the topic of gravity exclusively. Called You Know Gravity, the app tries to teach you everything about gravity, from the concept of gravity and upwards/downwards direction, to how you can control the orbital motion of a spaceship.

The Six Chapters

The content inside You Know Gravity is organized into six chapters. The first chapter lets you understand where downward direction is regardless whether you’re on a bus or in outer space. We know that gravity means downward on Earth, but it’s actually pulling towards the center of the Earth.

The app includes interactive experiments where you can see what would happen if gravity is just a simple 2D direction of going downwards. It allows you to play and experiment with different movements and settings to really grasp the concept.

You Know Gravity also teaches you about the different factors that affect gravity, namely mass and distance. It teaches you what would happen if you interfere with a moving object. You will learn how a force may change the direction of a moving object.

There are plenty of applications to gravity in this app. From seeing how hard the moon can hit the Earth, how small particles can form a star, and how to control the orbit of a spaceship.

Parents Need to Know

You Know Gravity is the third app in the Visual Science series, the first being You Know Moon Phase. The latter lets you learn the different phases of the moon. Similar to this app, You Know Moon Phase uses 3D simulation to explain the concepts related to the topic.

The app works great without an Internet connection. It doesn’t have any third-party ads, in-app purchases, or links to social networks. Do note that the app is built for the newer hardware, and support is only provided for iPhone 5/iPad or higher.

You Know Gravity allows you to play, experiment, and observe natural phenomena through its in-app simulation to help you grasp the concept.

Things I Like

Based on its definition, science is the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment. Without practical experimentation, learning science can’t really be considered complete. That’s why allowing kids to play, experiment, and observe is a key success factor for a science app.

You Know Gravity allows you to repeat any natural phenomena until you grasp their principles. Through a series of well-designed experiments, you can observe and draw conclusion on why such phenomena occurs. Using a step-by-step approach, the app aims to guide you through each concept gradually and thoroughly.

There are six scenes that you can play with and learn from. You can choose to navigate to any screen at anytime.

Conclusion

You Know Gravity is a unique app that offers kids ages 7+ a way to experiment with gravity. This includes everything from the basics of figuring upward and downward directions to controlling the speed and direction of a spaceship to orbit the Earth in a specific way. Even though gravity on Earth can easily be practiced without any app, tinkering with the Earth’s gravity from an outer space perspective makes this app worth considering.
