Identify in each case whether work done in each case is negative, positive or zero by givingappropriate reason in support of your answer (in notebook)-(i) Work done by the gravitational force of earth acting on a satellite moving around it in acircular path(ii) A man of 60 kg carrying a luggage of 80 kg on his head waiting for the train on platform.(iii) A squirrel going up a tree.(iv) An engine is pulling coaches of train.(v) A body falling freely due to force of gravity

In which of the following cases will work NOT be done on an object by the action of a force?When the object is moving very slowlyWhen the magnitude (size) of the force changes with timeWhen the force which is acting is small compared to the weight of the objectWhen the object does not move in the direction of the force2Which of the following will cause one joule (1 J) of work to be done on (energy to be transferred to) an object?A force of 1 N causing the object to move through a distance of 1 cmA force of 10 N causing the object to move through a distance of 10 cmA force of 100 N causing the object to move through 10 mA force of 5 N causing the object to move through 0.1 m3

A book is resting on a horizontal table. When you push the book horizontally and let go, you observe that the book moves for a while and then stops. Which of the following statements is correct?Group of answer choicesthe book stops because a non-zero net force was working on it before stoppingthe book stops because it is the inherent property of all objects to come to restthe book stops because it does not want to fall from the tablethe book stops because the normal force on the book is equal to its weightthe book stops because the earth is pulling it down

A force is applied to an object, causing it to move. The direction of the force and the direction of the motion are at an angle between parallel and perpendicular to each other. Which statement best describes the result of the work done in this situation?Multiple choice question.The work will be between zero and the product of the force and distance.The work will be zero.The work will be equal to the force multiplied by the distance.The work will be equal to the force divided by the distance.
