This kind of mechanism is very commonplace in machines. Machines are made up of a number of parts and relative motion between the various parts permits the working of the machine. As the crank is rotated the rod starts moving but the velocity is not uniform. It is greater towards one direction than the other. This principle is utilized extensively in some machines. Aim Understand the relative motion of the rotational and sliding joint. Understand the movement of the rotational and sliding joint

Zachary Bishop The effect of distance between dominoes and time taken to fall Introduction By collecting data whilst keeping all variables constant apart from the independent and dependent variables of an experiment‚ it is possible to determine a relationship between them. One relationship that can be observed in a laboratory is the relationship between the distance (denoted by symbol d) of separation of dominoes in a domino chain and the time taken (denoted by symbol t) for all dominoes to fall

Relative Clauses - Exercises 1. Re-write the sentences so that they have the same meaning as the original. You must use a relative pronoun. a. I bought a house. It was advertised in the local paper. b. Mary works in our office. Her husband is a plastic surgeon. c. Venice is a wonderful place. We spent our last holiday there. d. He showed us how to create a computer-based game. It was very interesting. e. I’ve just finished reading Harry Potter and the Philosopher’s Stone

the time taken by the train to cover (l + b) metres. 7. Suppose two trains or two objects bodies are moving in the same direction at u m/s and v m/s‚ where u > v‚ then their relative speed is = (u - v) m/s. 8. Suppose two trains or two objects bodies are moving in opposite directions at u m/s and v m/s‚ then their relative speed is = (u + v) m/s. 9. If two trains of length a metres and b metres are moving in opposite directions at u m/s and v m/s‚ then: The time taken by the trains to cross each

observer in an accelerating frame of reference can perceive its motion. Passengers in a car‚ for example‚ fell themselves pressed backward if the car starts suddenly from a dead stop. Their awareness seems to imply that acceleration is absolute‚ not relative; they need not refer to anything outside their frame of reference to detect their own motion. But if accelerated motion is absolute‚ it would have to be subject to a different set of

1. Suppose that an open box is to be made from a square sheet of cardboard by cutting out 6-inch squares from each corner as shown and then folding along the dotted lines. If the box is to have a volume of 486 cubic inches‚ find the original dimensions of the sheet of cardboard. 2. A toy rocket is shot vertically upward from the ground. Its distance in feet from the ground in 5 seconds is given by s(t) = -16t2 + 169t. At what time or times will the ball be 162 ft. from the ground? Round your

it is common to assume that the velocity of money is constant. The velocity of money is a measure of average number of times per year that a dollar is exchanged. The quantity theory of money states that the money supply multiplied by the velocity of money is equal to the price level multiplied by output. ( ) Price level multiplied by output is the nominal output. Therefore‚ a percent change in the money supply added to a percent change in the velocity is equal to a percent change in nominal

<center><i>The Fundamental Principles of Relative Dating</i></center><br><br>Relative dating involves placing events in their proper chronological sequence‚ that is‚ in the order of their occurrence (Dutch 1998). This type of dating tells us which geologic event happened first‚ but does not give an exact date to which something happened. There are several different methods that are used in relative dating. These are the fundamental methods that are used in the field by geologists ’ and earth scientists

“Deviance is relative” – Evaluate. Deviance is actions that seem to be abnormal or go against the norms and values of society. What is deviant largely depends on a situation so it is relative. This means that it is only deviant in certain places at certain times or in certain cultures. There are three types of deviance‚ cross cultural‚ situational‚ and historical. Cross cultural deviant is some cultures but not in others for example in the UK it is seen as normal to wear shoes inside your

Mass Affecting Final Velocity Name: Anlin Pereira Class: 11C The lab was conducted on 24th September 2014 Teacher: Ms. Timlin Research question: How does the mass (grams) affect the final velocity (m/s) of the toy car on a one meter ramp? Aim: To carry out an investigation to prove that factors such as mass (grams) affects the final velocity (m/s) of an object as it travels a straight line and has a constant acceleration (m/s²). Hypothesis: It is predicted that the mass of the moving object
