App Description

Go beyond the standard textbooks and take learning to the next level. Take part in scientific explorations, interactive exercises—and do it all right there on your device!

Discover the motion of a projectile launched horizontally, from a height. Explore the variables that affect the motion of such a projectile. Change each variable in a dynamic simulator and see the results.

• Launch human cannonballs of different masses horizontally and observe their motion.
• Make predictions about the motion of the projectiles.
• Use the challenge mode to launch your cannonballs to that they reach the ground at exact distances.
• Use the data tables to keep track of prior shots.

App features:
• Manipulate an interactive simulator to explore projectiles launched horizontally.
• Make predictions and observations and receive helpful feedback.
• Watch animations that explain the concepts.
• Test your knowledge with interactive tasks and quizzes.
