Forces Playground vs Motion
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Forces Playground
Explore how different forces impact objects in a simulated space environment. Users can add objects and apply gravity, anti-gravity, or vortex forces to observe their effects. Adjust force strength and object mass to create unique physics interactions.
- Apply gravity, anti-gravity, and vortex forces
- Adjust force strength and object mass
- Observe object interactions in real-time
- Clear and reset the scene
- Show or hide forces

This great App shows how forces affect objects in space! Drop objects into the scene and put forces in the scene to affect the objects! Demonstration of gravity, anti-gravity and vortex forces with images dropped in to the screen that get attracted to the forces when the users touches. The user can select Vortex, Gravity or Anti-Gravity forces and watch the fun in this physics simulation! Vortex will cause the objects on screen to rotate around. The user can increase or decrease the vortex forces on screen so the rotate left, stop or rotate right. The user can also increase or decrease the gravity forces on screen. Gravity will attract objects on the screen. Anti-gravity will repel objects on the screen. The user can increase or decrease the mass of the colored squares on screen by swiping up or down. Reset color mass to defaults by swiping left. Clear the screen by swiping right. Show or hide forces by pressing the buttons on the top of the screen. Special Thanks to NASA for the public domain images used for the Space pictures!

The Motion- Physics K12 educational app helps kids to understand about motion, distance, time and speed. Our app makes it easy for students to Identify how the acceleration of a moving object changes with time by using high-quality professional animations. There are three sections in the app: Learn: This sections explains the complete details about motion (change in position of object) and illustrates about Distance, Time, Speed, Velocity and Acceleration. An animated speed - time graph shows how the speed of a moving object changes with time and a velocity - time graph shows us how the acceleration of a moving object changes with time. 2) Practice: This section help students to identify speed and velocity of the vehicle with high-quality graphs. 3) Quiz: An interactive quiz to check the knowledge on motion, speed, velocity and time with score board. Download the motion app and other educational games published by Ajax Media Tech. With the gamified education model, students will be able to absorb and learn the fundamentals and basics with minimal efforts and maximum retention.
