Laboratory – Terminal Velocity Introduction: Consider dropping a piece paper and a brick from the same height. Although in theory they should both strike the ground at the same time; in practice the brick will always strike the ground first. The reason is because of air resistance. As the paper falls to the ground air resistance is pushing the paper up‚ this slows the acceleration of the paper. It is known that as the velocity of an object increases the air resistance acting on the object

resistance is stronger then the terminal velocity that is when the object is going at a small velocity. Terminal Velocity When there is equal force acting on an object when falling such as gravity and air resistance at that stage it is called constant speed or terminal velocity. When the object is dropped the force of gravity initially is 100% but as it falls the air resistance becomes stronger making the gravity weaker and at one stage there will be terminal velocity. In some cases due to the

Determine the time it takes to reach the ground. Answer: t 2 1 6 sec. A particle is dropped from the top of the tower of height h. At the same instant another particle is projected vertically upwards from the bottom of the tower with such a velocity that it will be able to just reach the top of the tower.

All of the officers worked very carefully to check every passanger’s luggage. One day‚ a person came from Krakhozia‚ a country which in the middle of a war. His name was Victor Navorski. According to the rules‚ he neither could went to New York nor back home. He met the head of the airport‚ Frank Dixon‚ to solve his case‚ but the regulation kept him to stay in the airport

Introduction: This lab is an experiment in terminal velocity‚ the speed an object cannot surpass due to frictional forces. To begin‚ it is important to note that the objects in this lab are not in a free-fall scenario. A free-fall scenario is a situation where an object is dropped in a frictionless environment‚ and the only force that is acting upon it is the force of gravity. In a free fall environment‚ terminal velocity would not occur‚ because no frictional forces would act on the object to

Both magnitude and d_________________ are important. Example 1 A car travels 5 km due east and makes a U-turn back to travel a further distance of 3 km. Find (a) the distance covered‚ (b)
