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.
