The astronomer Johannes Kepler was the first scientist to explain that the eye works by focusing an image of the outside world onto the retina. However, we can see floaters just in front of the retina and white blood cells moving in the capillaries on the retina because of the shadows they cast and the light they let through. No focusing of an image is involved. Can you think of any other things and ways we might see that also do not rely on the focusing of an image on the retina?

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
