Here is the link for my prezi: media type="custom" key="11273430"

Good use of the Prezi. A couple of things: First of all, there are no sample calculations (-4). Second, the relationship is inverse not indirect. Lastly, the inverse graph should be a curve. Since yours was straight you need to attempt to explain that. 24/30

Chapter 5 bonus question

Your presentation was good in some aspects. However, you state that the force must be the acceleration. Force and acceleration are two different things. You also state that gravity can not pick and choose which objects to pull harder on. That is not true. There is a greater force of attraction between more massive objects. The point is that the the force on the 7 kg ball is 14 times greater than the force on the 0.5 kg ball. Since acceleration is directly proportional to force the acceleration should of the 7 kg ball should be 14 times greater. However, acceleration is inversely proportional to the mass so the acceleration on the 7 kg ball would be 1/14 that of the 0.5 kg ball. Therefore, the acceleration of the 7 kg ball is equall to the acceleration of the 0.5 kg ball. +4
