4 2020 SNGS Year 4 IP Physics EOY Exam P1 5 6 The diagram shows an aeroplane turning in a horizontal circle at constant speed. In which direction is the aeroplane accelerating? A stone is falling through the air. The acceleration of free fall is 10 m/s2. Ignoring air resistance, what happens to the stone each second during its fall? A The acceleration of the stone increases by 10 m/s2. B The speed of the stone increases by 10 m/s. C The stone travels a distance of 10 m. D The stone travels at a speed of 10 m/s. 7 Two blocks are connected by a light string S . Under the action of a constant force F, they move with a uniform acceleration of 2.5 m/s2. What is the acceleration of the 4 kg mass if string S suddenly breaks? A 3.75 m/s2 B 5.00 m/s2 C 7.25 m/s2 D 10.0 m/s2 S

5 2020 SNGS Year 4 IP Physics EOY Exam P1 8 9 Which statement concerning the mass of a body is not correct? A student tries to find the density of sand by filling half a container with sand and the other half with water (assuming the sand and water do not mix) . The diagrams show the set-up and data she collects in her experiment. A The body experiences a force in a gravitational field because of its mass. B The mass is a measure of the amount of matter in the body. C The mass changes when the strength of a gravitational field changes. D The mass resists a change in the state of rest or motion of the body. Taking the density of water as 1.0 g/cm3, calculate the density of the sand. A 1.6 g/cm3 B 1 .9 g/cm3 C 2.0 g/cm3 D 2.7 g/cm3 80 g 200 g 300 g empty container container filled with water container with sand and water
