represents part of the Solar System. Sun planet A planet B Jupiter Uranus Neptune Saturn Earth Venus (not to scale) State the name of planet A and the name of planet B. planet A planet B On , draw an X to represent a moon of Jupiter. Draw a line to show how this moon moves. State two ways in which the four planets nearest to the Sun are different from the four planets furthest away from the Sun. Complete the following sentences: The galaxy that includes the Solar System is called the . The includes billions of galaxies. The distance between the Sun and the Earth is 1.5 × 1011 m. The speed of an electromagnetic wave is 3.0 × 108 m / s. Calculate the time taken for an electromagnetic wave to travel from the Sun to the Earth. time taken = s

shows the Sun as the central dot and the planets Saturn, Jupiter and Earth labelled S0, J0 and E0. The planets orbit the Sun anticlockwise. From the Earth’s orbit, the planets appear aligned. E0 J0 S0 (not to scale) Assume that Saturn takes 30 years to orbit the Sun and that Jupiter takes 12 years to orbit the Sun. On , mark the positions of Saturn and Jupiter 5.0 years after the original positions shown. Label these positions S1 and J1. Show your working. On , mark the positions of Saturn and Jupiter 20 years after the original positions shown in . Label these positions S2 and J2. State what is observed from the Earth’s orbit after 20 years. Choose two words from the list to describe each planet. gaseous large rocky small Jupiter Earth The average density of Jupiter is much less than that of the Earth. The gravitational field strength at the surface of Jupiter is greater than that at the surface of the Earth. Explain how these differences in density and in gravitational field strength are consistent with your answers to . density gravitational field strength The average density of Jupiter is 1300 kg / m3 and its volume is 1.4 × 1015 km3. Calculate the mass of Jupiter. mass =

In , a small bird, a large bird and a squirrel are on the ground under a tree. A loud noise scares the two birds. They both fly up to the top of the tree. Which bird does the most work raising itself to the top of the tree? Explain your answer to . A squirrel has the same weight as the large bird. It climbs the tree, to the same height as the birds. How does the increase in the squirrel’s gravitational potential energy compare with that of each of the two birds? Answer the question by completing the sentences below. Compared with that of the small bird, the increase of the squirrel’s potential energy is . Compared with that of the large bird, the increase of the squirrel’s potential energy is . Which creature has the least gravitational potential energy when they are at the top of the tree? The small bird flies back down to the ground. What happens to the gravitational potential energy it had at the top of the tree?

shows remote sensing equipment on the surface of a distant planet. The mass of the equipment is 350 kg. The acceleration of free fall on the surface of this planet is 7.5 m / s2. State what is meant by the term weight. Calculate the weight of the equipment on the planet. weight = The equipment releases a balloon from a point that is a small distance above the surface of the planet. The atmosphere at the surface of this planet has a density of 0.35 kg / m3. The inflated balloon has a mass of 80 g and a volume of 0.30 m3. Make an appropriate calculation and then predict and explain the direction of any motion of the balloon. Show your working. prediction explanation
