Students in 4th period should look over my annotation in the prior three classes...- Ms. Todd

Teacher: Please write in nearly complete sentences and watch your spelling. You can discuss things with each other and with me... Keep to our topic. Teacher: First, how did gravity affect the distance that the balloons went? John: the gravity affected affThe gravity will make the balloons drop faster and harder Bailey: the higher the gravity, the faster it drops Jen: Gravity seems to have the least affect on the balloon. It tells the balloon how fast to drop, but the velocity seems to overpower the gravity sometimes. Alexandre: A larger gravity is a shorter throw. JasonC: gravitymade the ballon heavy. elizabeth: More gravity makes it drop closer to the building, but you need a lot of change to make very much difference Alexandre: Shorter gravity is a more arced and longer throw Teacher: How does gravity affect the weight of the object? Sahil: The larger the Gravity the faster the object drops Bailey: the object stays the same JasonC: the water in the ballon. elizabeth: The heavier the object the faster it will drop Teacher: Jason, clarify... John: if the gravity is high the object will weigh more since the air is harder to move Ian: The higher the gravity the heavier the object Alexandre: Adam Says : More gravity makes the balloon heavier JasonC: by how much water was in there Rachel: Decreased gravity allowed the projectile to be launched further because the force longer pulling down on the object takes longer to affect the object. griffin: the weight of the object does not change, but the atmosphere around it affects the distance Alexandre: Less gravity makes the ballon lighter Alexandre: balloon Bailey: i agree with rachel elizabeth: The weight changes, the mass doesn't Teacher: OK so how does velocity affect the distance...? Jen: gravity makes the object seem heavier and go shorter distance. if there is high gravity then the balloon drops faster. low gravity makes the balloon drop farther out from the starting point Alexandre: more velocity, longer distance, adam says elizabeth: I agree with Jen. Alexandre: less velocity shorter distance, alex says Jen: The velocity makes it go farther and have the most control. The other 3 variables can be anything and the balloon will still go far because of velocity. JasonC: the water in ballon shows how far it goes. Bailey: the more velocity, the farther the object goes!!!!!!! : ] Ian: - Velocity affect how fast the water balloon is thrown John: The velocity also helps how far it goes and how high it goes. For example if you through a baseball harder it will move faster and there for go farther. Rachel: The weight changes based on gravity, a perfect example of this is weight on earth compared to weight on the moon. Sahil: velocity is how fast the projectile goes and how far it goes, says i elizabeth: A higher angle makes it go higher at first, but then it drops closer, but Meredith points out that if you do it too low it slants down faster. JasonC_Franklin: hi Bailey The less velocity, the shorter the disntance Teacher: What about the angle...? How does it affect distance? Megan: The angle affects how far the balloon goes up or down, and then drops, usually at a slant depending on the angle. However angling it to high or to low will cause the balloon to go straight down. John: The angle effects a lot on how far and high it will go. For example if u do it 90 degrees it will go straight up then down Alexandre: Larger angle less distance less arc Jen: The angle decides at what height the balloon travels. If the balloon travels very high then the balloon lands closer to the building if it the angle is lower it tends to go farther. Ian: Angle affects your distance, the higher the angle the shorter distance the water balloon goes Alexandre: smaller angle more distance morw arc Alexandre: more Sahil: Angle is what direction the object goes and how high and far Teacher: So clarify...the greater the angle...what kind of distance...? Sahil: the farther distance Bailey: the higher the angle over 90 degrees, the further it goes/ the less the angle under 90 degrees the further it goes Rachel: By decreasing the angle the object goes further, maybe, I don't know. Jen: the greater angle the more arch which makes the object land closer JasonC_Franklin: I RULE THE WORLD! griffin: greater angle, less distance Alexandre: less distance elizabeth: It depends, because too high and it doesn't go far, but too low won't make it go far. It needs to be somewhere in the middle. Megan: You have to adjust it a little above or below 90 degrees but if you adjust it too much it will go straight down Teacher: Now how about the wind. If you threw anything into the wind, how might it be affected? Could it come flying back into you? Alexandre_Pauwels: so greater the angle, lesser distance, maybe Neal: the wind can either make the object move faster or slower griffin: wind affects speed and distance Alexandre: a good angle can get you good throw elizabeth: If you have negative wind, it goes normally at first and then it blows back against the building. John: The wind also effects the speed and the angle. Another example is in golf If there is a lot of wind it will throw your balls angle off and speed, which can be a begative if your trying to hit a good shot. Alexandre: Adam Says: possitive wind, so right wind, makes a longer throw Teacher: What if the wind is blowing directly at you? griffin; it willblow the object back at you elizabeth: It will land behind you. Bailey: no, the water balloon could not go back into you because if the wind is going the way u r throwing, it wouldnt Alexandre: Adam Says: negative wind, so going in ur face, makes a lesser distance John: if the winds velocity is faster then the object could go backwards elizabeth: It depends on how hard the wind is blowing wether it will go forward first then blow behind you, or if it will just go right behind you. Jen: The wind can have an affect but gets over powered by the other variables a lot of the time. So I don’t think it would make a huge difference Bailey: it depends on the speed of the wind, and the weight of the projectile Jen: i agree
