Projectile Motion in Practice

If you looked up to the veranda outside the Visual Arts classroom last week, you may have been a little perplexed as to why students were flinging bags of lollies from between the railings.

The students were in fact conducting investigations as part of their Physics course.

The first module of the Year 12 Physics course (Advanced Mechanics) features a unit on Projectile Motion.  Students worked together using two small objects, packaged lollies and a ruler, to devise a test to dispel the common misconception regarding the fall time of projectiles.

They were able to show that an object given an initial horizontal velocity, and an object falling directly to the ground, both land at the same time!
