Introduction to Free Fall app for iPhone and iPad

Study the how gravity affects free fall in an interactive environment. Complete experiments, answer questions, make predictions, and take quizzes—learn science in a whole new way.

Learn about the factors that affect the motion of a ball in free fall. Manipulate a dynamic simulator which allows you to change all variables involved.

• Choose different types of balls with different masses.
• Determine the height the ball will be released from.
• Determine the gravitational acceleration acting on the ball.
• Measure the time it takes for the ball to reach the ground.
• Record all your observations in an experiment report.

App features:
• Explore which factors affect the motion of an object in free fall.
• Use a dynamic simulator which can change all involve variables.
• Watch animations that explain the concepts.
• Test your knowledge with interactive tasks and quizzes.
