energy
light bulb
If 10 kilograms of matter spontaneously turned into energy there would be enough energy to power a 100 Watt light bulb for 300 million years – a harrowing thought for all weight watchers.
force
supernova
A supernova is the most energetic single event known in the Universe. Material is exploded into space at a speed of about 10,000 kilometres per second and the energy emitted is 1044 Joules. Our galaxy contains about 100,000,000,000 stars and all these stars would have to shine for six months to produce this much energy.
motion
orbit
The orbit of the Moon about the Earth would fit easily inside the Sun.
elements
gold leaf
Gold leaf is pure gold, but you can cover large areas with it very cheaply because it is very thin. Gold leaf is less than 0.00008 millimetres thick - which is only about 300 atoms thick.
money
Paper money is made from cotton rather than from wood pulp which means it doesn't disintegrate as easily as ordinary paper if you leave it in your laundry.
meteorite
The mass of the Earth increases every year because of the 3,000 tonnes of meteorite debris that hits its surface from space.
