Food contained internal energy which is sometimes called chemical energy]]> 2018-02-01 08:55:38 UTC https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226935971 tsaeed17 https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226974645 In a series circuit, the more lamps you put in, the dimmer each one is. Also, in a series circuit, if a lamp breaks or a component is disconnected the entire circuit is broken and the whole circuit stops working. Series circuits are useful if you want a warning that something in the circuit is broken and they also use less wiring than a parallel circuit.]]> 2018-02-01 11:12:18 UTC https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226974645 tsaeed17 https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226977373 circuitIn parallel circuits, different components are connected on different branches of the wire. If you follow the circuit diagram from one side of the cell to the other, you can only pass through all 5e different components if you follow ALL the branches. If a lamp breaks or a component is disconnected, the components in different branches keep working. Also, unlike in a series, the lamps in a parallel stay bright no matter how many you add. Our homes are wired up with parallel circuits.]]> 2018-02-01 11:24:01 UTC https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226977373 tsaeed17 https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226978140 The energy in food can be released by burning it or by eating it. The labels on packaging show how much energy is in food. 215 calories (for example)]]> 2018-02-01 11:27:06 UTC https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226978140 tsaeed17 https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226997116 All moving things have kinetic energy - from a planet to an atom. All objects have thermal energy however it will increase dependent on the temperature e.g a hot cup of tea has more thermal energy than a cold cup of tea. Rubber bands and springs have elastic potential energy. When an object is moved higher, it gains gravitational potential energy. The amount depends on: the mass of the object, the extra height it gains and the gravitational field strength.]]> 2018-02-01 12:39:21 UTC https://padlet.com/tsaeed17/39zdjri8nkeo/wish/226997116
