Answer 21.
\n(a) <\/strong><\/p>\n\n- An object has some mass \u2018M\u2019, when it is raised through a certain height, energy is applied on it, this energy gets transformed and is gained by the stone. Hence its energy increases.<\/li>\n
- Energy is present in every object in some or the other form, it exist in Sun, planet, wind, water etc. Energy gets transformed and because of its transformation we get it into different form.
\nFor example, Sun \u2018s energy \\(\\xrightarrow [ byplants ]{ Converted }\\) Food \\(\\underrightarrow { Oneating } \\) Energy to our body.<\/li>\n - Work is said to be done, when force is applied on the body and it moves to a certain distance. When a wall is pushed there is no displacement and we say that work done is zero.<\/li>\n<\/ol>\n
(b)<\/strong> Kinetic energy is the energy present in a body by virtue of its motion. When water is stored in a dam at particular height, we say it has maximum potential energy as the water is present at a height.
\nWhen this water is allowed to fall down from a certain height, it is said to have kinetic energy. When water falls on the turbine, the paddle wheels rotates to rotate the turbine. Hence kinetic energy of water is used to push or rotate the turbine which is further used to produce the electricity.
\nOR<\/strong><\/p>\n(a)<\/strong> Law of conservation of energy states that energy can neither be created nor destroyed, but it can be transferred from one form to another. The total energy before and after transformation remains the same.
\nLet the body be at position A from the ground level. It has the potential energy, PE. When the body falls down and reaches in the middle, P.E. = K.E. and when the body is just about to touch the ground its K.E. > P.E. This shows that P.E. is getting transferred into kinetic energy.<\/p>\n![\"CBSE](\"https:\/\/www.aplustopper.com\/wp-content\/uploads\/2018\/12\/CBSE-Sample-Papers-for-Class-9-Science-Paper-4-Q.21.2.png\") <\/p>\n
