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:
