Identifying Forces app for iPhone and iPad

There’s a new, engaging way to learn and apply your knowledge of science in a dynamic environment. Learn by doing and see the impact of being involved in what you learn.

Analyze the forces acting on a system and construct free-body diagrams. Learn that forces are vector quantities, and that free-body diagrams represent the magnitude, direction, and types of force(s) acting on a system.

• Draw free-body diagrams to analyze forces acting on a chair that is being pushed.
• Practice constructing free-body diagrams for five different systems.
• Learn about different forces that can act on a system.
• Explain that forces are vector quantities that represent magnitude and direction.

App features:
• Apply the physics of forces acting on a system in a series of hands-on exercises.
• Watch animations that explain the concepts.
• Test your knowledge with interactive tasks and quizzes.
