Physics with GeoGebra

• 6 Interactivities for Learning about Centroids of Triangles
  • What's a median of a triangle?
  • What's special about medians of triangles?
  • Exploring Centroids
  • Interact with Ceva's Theorem
  • Six triangles with equal area that don't look alike at all!
  • 2/3 and 1/3 - how is that possible?

• Activity 6 - Vertical Motion - Firing the Cannon Straight Up
  • no parametric equations
  • Wide Version (1280x1024)- Try it!
  • Standard Resolution (1024x768)- Try it!

• Activity 5 - Firing the Cannon - Plus: Set the Gravity
  • Wide Version (1280x1024)//

• • Standard Resolution (1024x768) - Choose your Planet: Try it!

• Activity 3 - Firing the Cannon
  • Try it!

Learning in this activity: User can set the angle and watch the cannon tilt, the height and the initial velocity and then fire the cannon and watch the cannon tilt and then the trajectory of the cannon ball and have it explode (and see the equations and the data).
