Unit of work is Joule (J), Kilojoule (KJ) The factor affecting work done are force (F) and displacement (S)Įquation for calculating work done Work W = Fs Another boy pushed the same body through 30m on the same floor with the same speed.ĭ) Which is the factor influencing work here?ĭ) The Factor influencing work is displacement Both of them gave the same speed for moving the objects.ī) More work is done in the second situationĪ boy pushed an object of mass 30kg across a horizontal floor through 20m. Another boy pushed an object of mass 50kg across the same floor through 50m. A boy pushed an object of mass 30Kg horizontally across the floor through 50m.
The person loaded on head and goes upward.ĥ to the 9th Power Question 5. Observe figure and write down the situation where work is said to be done Work is said to be done only when a body under¬goes displacement in the direction of the applied force. A car is pushed by sitting inside the carģ. No displacement for the body in the direction of force appliedĢ. Displacement takes place in the direction of force applied Objects undergo displacement only when the force is applied on it them. Find out the source of applied force for every activity and note them down in the table. You have understood that a force is to be applied on a body to do an activity. Write down more activities familiar to youĬhapter 5 How it Works Question 3. Observe figure try to write down the activities shown in them.
