Continue decreasing the value of D, by using successively smaller pieces of cardboard. Data and Calculations For each value of D, calculate the average of t1 through t5. Record this value as tavg. Calculate vavg = D/tavg. This is the average velocity of the glider in going between the two photogates.
FOR LANDING THRUST MUST BE LESS THAN DRAG, AND LIFT MUST BE LESS THAN WEIGHT. THE FOUR FORCES ACTING ON AN AEROPLANE AN AIRPLANE IN FLIGHT IS THE CENTRE OF A CONTINUOUS TUG OF WAR BETWEEN FOUR FORCES: LIFT, GRAVITY FORCE OR WEIGHT, THRUST, AND DRAG. LIFT AND DRAG ARE CONSIDERED AERODYNAMIC FORCES BECAUSE THEY EXIST DUE TO THE MOVEMENT OF THE AIRCRAFT THROUGH THE AIR. THE WEIGHT PULLS DOWN ON THE PLANE OPPOSING THE LIFT CREATED BY AIR FLOWING OVER THE WING. THRUST IS GENERATED BY THE PROPELLER AND OPPOSES DRAG CAUSED BY AIR RESISTANCE TO THE FRONTAL AREA OF THE AIRPLANE.
· the plant has poison on it so scavengers do not eat it. 2 examples of scavengers · the ducks scavenge for bugs in the lake. · the flys scavenge for food or animal waste. Example of a Plant Reproduction · The plant has seeds that fall out and start to grow other plants. Example of symbiosis the fly and duck: the ducks eats the fly and gets energy.
Like at the bottom of the first hill as the car goes up the hill gravity pulls on it, so that it decelerates. And in the first hill as the coaster train goes down gravity tends to pull it down towards the ground as it accelerates. Like in Newton’s first Law – an object in motion must stay in motion.
Two quotes from “A Sound of Thunder” that represent this theme are “Embedded in the mud, glistening green and gold and black, was a butterfly very beautiful and dead” (pg. 299) and “It fell to the floor, an exquisite thin, a small thing that could upset balances and knock down a line of small dominoes and then big dominoes and then gigantic dominoes, all down the years across time.”(pg. 299), these quotes represent the theme because they show that one little thing changed the future entirely. This theme represents science fiction because if time travel were real, scientific date can prove that things could be changed very
Winds exceed 205 mph. Conclusion In this speech I have explored what cause tornadoes to develop, how researchers classify types of tornadoes. So the next time, you see your college dorm being dismantled floor by floor, or a chicken without wings, take cover because tornado season is here. References Davies-Jones, R. (1995). Tornadoes: The storms that spawn twisters are now largely understood, but mysteries still remain about how these violent vortices form.
Due to this convergence (where winds move to a center point), air is forced to rise over that area. If enough moisture is available, the rising air cools and condenses (as cold air cannot hold water vapor below a certain temperature) into tiny water droplets which constitute the cloud. So, low pressure areas are usually the birth-place of clouds. Sometimes, particularly in the winter, fog forms over a high pressure area due to radiation cooling(due to clear sky conditions over a high pressure area).This fog sometimes lift and forms thick low cloud called "anticyclone gloom".

Activity 4: If you put a pile of tin plates on the top of the generator’s globe, they will fly off one at a time. Since each of them will be picking up some of the excess charges the plates repel each other and they will fly off one at a time. Activity 5: A piece of tinsel or Christmas tree icicles will first be attracted to the globe by induction, just like when you stick a charged balloon to the wall, and then repel away from the generator after it picks up some excess charge. Activity 6: If you start with your hands on the globe and then turn the generator on you won’t get a shock, because the charge doesn’t get a chance to build up. The charge will continually leak into you and then through you to the ground.
So you see, Newton's 3rd law can explain your balloon powered car. air shoots out the back at high speed and the car moves forwards (more or less) at low speed. So the force used to accelerate all that air backwards has an opposite force on the balloon (reaction) which is tied to the car so pushes in the opposite direction. Well the air's coming out fast in the beginning but thats when the car is only just moving, it takes a while to speed up and it takes even longer if you have a heavy car. So you may be able to argue it shows that f is proportional to Mass x acceleration (but to be honest I think that would be stronging it a bit - balloons don't seem to give very constant thrust.
Lord of the Flies Government Essay Lord of the Flies, by William Golding, describes a horrific plane crash involving several young English boys deserting them on an island. The events in Lord of the Flies relates to the United States government. The author does this by starting out the story with the boys landing on the island, and once all together, then try to plan a way of how things will work in order to survive. This is the start of how the Articles of Confederation began, leading into the Constitutional Convention where the Constitution was born. The Articles of Confederation due to having too weak of a central government, where people were in need of a stronger government.
