9.2 Space Students learn to: Students: 1. The Earth has a gravitational field that exerts a force on objects both on it and around it define weight as the force on an object due to a gravitational field perform an investigation and gather information to determine a value for acceleration due to gravity using pendulum motion or computer-assisted technology and identify reason for possible variations from the value 9.8 ms-2 gather secondary information to predict the value of acceleration

This world is not without problems. Many forms of problems are a part of the human life in this world. One of the considerable forms of problems are addictions; more specifically‚ video game addiction. This addiction is one of the growing worries among children and adults. There is now a new method of treatment called video game detox. There is one treatment centre in Amsterdam which employs this method to their subjects. They are forced to quit gaming cold turkey. They start on this treatment

between the armor of the enemy knights also they were used to throw hot tar to attack there enemies. It was also used to launch infected bodies into enemy camps to spread disease. Although they are very hard to create‚ they use very simple forms of physics to complete their task of destruction. The catapult has a basket or cup on the end of a movable arm strong enough and large enough to hold the weight of the object it is intended to hurl. Tension is applied to the arm‚ whether that be applied by

Case 1 What performance problems is the captain trying to correct? In the case study the police captain is having difficulty getting the police officers to perform required tasks accurately. Task performance is crucial since it refers to goal-directed activated tasks that are under the individual’s control. The main issue is the behaviour and the result. The behaviour includes police officers not doing detailed and unambiguous paperwork. Since most the police officers are young they enjoy more

AP10005 Physics I Tutorial 7 (Chapters 17‚ 18) 1. (17P11) A flower pot is knocked off a window ledge from a height d = 20.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h =1.75 m who is standing below. Assume the man requires a time interval of Δt = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? 2. (17P15)

The physics of scuba diving Imagine swimming in the underwater world with all the creatures and all the beauty it holds. It is an amazing feeling to swim over coral reefs and see all the sea life up close and personal. So many scuba divers all over the world share a passion to scuba dive. Scuba diving has been a worldwide endeavor for centuries (1). Persian divers were making goggles for diving around 1300. A British engineer invented the air pump in 1771 and in 1772 a Frenchman tried inventing
