It includes scenarios such as a model air-powered rocket, a cyclist on a flat road, a tennis ball thrown vertically, and a student calculating power while running up stairs. The questions require students to relate velocity and speed, calculate kinetic and gravitational potential energy, determine maximum height using a given gravitational field strength, interpret velocity-time graphs with air resistance, analyse range patterns versus launch angle, and apply energy and power equations to practical situations.","Oasis Media City UK  \nEnergy  \nGravitational potential energy and kinetic energy  \nYear 10  \nOasis Media City UK  \nQ1 .  \n(a) Figure 1 shows the forces acting on a model air-powered rocket just after it has been launched vertically upwards.  \n(i) How does the velocity of the rocket change as the rocket moves upwards?  \nGive a reason for your answer.  \n______________________________________________________________  \n(2)  \n(ii) The velocity of the rocket is not the same as the speed of the rocket.  \nWhat is the difference between the velocity of an object and the speed of an object?  \n\n|  |\n| --- |\n|  |\n\n(1)  \n(b) The speed of the rocket just after being launched is 12 m / s.  \nThe mass of the rocket is 0.05 kg.  \n(i) Calculate the kinetic energy of the rocket just after being launched.  \nOasis Media City UK  \n______________________________________________________________  \n______________________________________________________________  \n______________________________________________________________  \nKinetic energy =   J  \n(2)  \n(ii) As the rocket moves upwards, it gains gravitational potential energy.  \nState the maximum gravitational potential energy gained by the rocket.  \nIgnore the effect of air resistance.  \nMaximum gravitational potential energy =   J  \n(1)  \n(iii) Calculate the maximum height the rocket will reach.  \nIgnore the effect of air resistance.  \nGravitational field strength = 10 N/kg.  \n\n|  |\n| --- |\n|  |\n\nMaximum height =   m  \n(2)  \n(iv) Figure 2 shows four velocity−time graphs.  \nTaking air resistance into account, which graph, A, B, C or D, shows how the velocity of the rocket changes as it falls from the maximum height it reached until it just hits the ground?  \nWrite the correct answer in the box.   \n(1)  \nOasis Media City UK  \n(c) The rocket can be launched at different angles to the horizontal.  \nThe horizontal distance the rocket travels is called the range.  \nFigure 3 shows the paths taken by the rocket when launched at different angles.
