3 4 The diagram below shows the velocity-time graph of a falling object. Which statement is true? A Air resistance caused the object to decelerate. B The acceleration due to gravity decreases with time. C The acceleration of the object at t = 0 s is 10 m/s2. D The object stops moving after 40 s. 5 Four of the gravitational forces that act between planets in our Solar System are listed below. W: the force on the Earth due to the Moon X: the force on the Sun due to the Earth Y: the force on the Moon due to the Earth Z: the force on the Sun due to the Moon Which two forces are an action-reaction pair? A W and Y B W and Z C X and Y D X and Z 6 Experiments are carried out on the Moon and on Earth. There is no atmosphere on the Moon and the gravitational field strength on the Moon is less than that on Earth. A coin and a feather are dropped at the same instant from the same height. Which statement is correct for the experiment on the Moon? A The coin falls faster than the feather, taking a longer time than they take on Earth. B The coin falls faster than
