TLF ID M016786
Students use this resource consisting of one page with diagrams of Mars, Earth and Jupiter. Students can select any combination of planets and then 'drop' the crates to note the effects of the different gravity forces because of the different masses of these planets. Students should be able to conclude that gravity is a force of attraction which acts on Earth towards the centre of the planet, and that the size of the force of gravity depends on the mass of each object (and the distance between them).
