Match the pairs. Group 'A' Group 'B' (1) Rolling object (a) Heat energy (2) Food (b) Atomic energy (3) Stretched bow (c) Kinetic energy (4) Sunlight (d) Potential energy (5) Uranium (e) Chemical energy

(1) Rolling object - (c) Kinetic energy A rolling object has kinetic energy. The kinetic energy is the energy that an object has due to its motion. (2) Food - (e) Chemical energy The food has stored chemical energy. When the bonds of compounds break in food due to the chemical reaction, it gives out energy. (3) Stretched bow - (d) Potential energy The energy possessed by a stretched bow is an example of potential energy that is in a body by virtue of its shape or position. (4) Sunlight - (a) Heat energy The sunlight contains heat energy. The heat energy from the sun is used in solar cookers to heat and cook food. Heat is also produced by the burning of fuel. Heat is commonly measured in the unit ‘calorie’. (5) Uranium - (b) Atomic energy The energy possessed by Uranium is an example of atomic energy. The heat liberated during the fission of atoms of heavy elements such as uranium, thorium is used to generate electricity.
