QUES: Force is a vector. What then is a vector? Think about how you would give directions to a friend. You would not say, just walk half a mile. The person may walk a half mile in the wrong direction! More information is needed. You may say, follow this particular road for a half mile. You may say, look for the green house on Sumter St. In both examples, you provided a direction. You also gave the distance. In other words, you provided a vector. You did not just give a distance. Both pieces of information are needed to find a location. This is just like describing forces. To explain forces, both size and direction are needed. Notice the girl in Figure 1.1. She is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push.

MY QUESTION: What does a strong push or a weak push have to do with force?

QUES: Dylan and Jez are two orphans who meet in their twenties and vow to achieve their shared childhood dream of living in a stately home .

During one of their biggest cons , their lives are touched by Georgie , who needs money to save the Down's syndrome foundation that her brother attends . When a con goes wrong , the two find themselves in gaol to be released only after their entire fortune is rendered useless because of a recall of 50 notes . It is down to an elaborate plan involving Dylan , Jez and Georgie , to break them out of gaol in order to save their dream . The film , in essence , is part Ealing comedy , part underdog farce with a sequence of madcap adventures set against a striking soundtrack by contemporary Britpop artists . Unlike straight rom-coms or mainstream comedies of the period Shooting Fish contained a generous blending of fact and fantasy .
