  1. A student investigates a pendulum.
    He measures the time for the pendulum to complete 20 oscillations.
    He repeats the experiment three more times.
    The readings are shown
  2. A tennis ball falls from the upstairs window of a house.
  3. A car joins a road at a speed of 14 m / s and accelerates at 4.0 m/s2 for 5.0 seconds.
    What is the final speed of the car?
  4. The gravitational field strength is 8.8 N/ kg on Venus and 3.8 N/ kg on Mars.
    An object has a weight of 42 N on Venus.
    What are the mass and the weight of the object on Mars?
  5. A student carries out an experiment to find the density of a rock
  6. A car has a mass of 1500 kg. A constant resultant force acts on the car and the car accelerates from 15 m/s to 20 m/s in 4.0 seconds.
    What is the magnitude of the resultant force acting on the car?
  7. A metal wire is loaded up to the limit of proportionality.
    Which statement is correct?
  8. The diagram shows a uniform metre rule, MN, pivoted at its midpoint P.
  9. Which physical quantity is a vector?
  10. A resultant force of 500 N acts for 10 s on a car of mass 1000 kg. This causes the velocity of the car to double.

  1. A child pushes a toy car along a horizontal surface and then releases it.
    As the car slows down, what is the main energy transfer?
  2. At time = 0, a cannonball is stationary inside a cannon. The cannonball is then fired from the cannon.
    At time = t, the cannonball moves forwards and the cannon moves backwards.
    What happens to the total kinetic energy and the total momentum of the cannon and the cannonball between time = 0 and time = t?
  3. In a small hydroelectric power scheme, 800 kg of water drops through a vertical height of 2.2 m every second. The electrical output is 10.6 kW.
    What is the efficiency of the scheme?
  4. An object is at rest on a horizontal surface.
    Which equation is used to calculate the pressure that the object exerts?
  5. Smoke particles, illuminated by a bright lamp, are seen through a microscope. They move about randomly.
    What causes this motion?
  6. Ether is a liquid that evaporates easily at room temperature.
    The rate at which ether evaporates can be increased by bubbling air through it.
    The diagram shows this process.
  7. Some ice is slowly heated and its temperature is measured. A graph is plotted of temperature against time.
  8. The diagram shows the apparatus needed for an experiment to determine the specific heat capacity of the material from which an object is made.
  9. Both boiling and evaporation involve a change of state from liquid to gas.
    Which row gives the correct difference between boiling and evaporation?
  10. Which statement describes thermal conduction in a metal by electrons?
  11. A tank contains water. Ripples are produced on the surface of the water. Refraction is observed.
    What causes the ripples to refract?
  12. The diagram shows wavefronts of a water wave passing through a gap in a barrier.
  13. The diagrams each show a ray of light from an object O passing through a thin converging lens.
    The principal focuses in each diagram are labelled F.
  14. The diagram shows a ray of light inside an optical fibre approaching point X.
  15. An eclipse of the Sun happens when the Moon comes between the Earth and the Sun.
    Which statement is correct?
  16. The diagram shows air particles in a sound wave
  17. Two isolated metal spheres are both negatively charged. The spheres are brought close together but do not touch.
    Which diagram shows the charge distribution on the spheres?
  18. Two separate circuits have different power supplies. Both power supplies provide the same magnitude current.
    Power supply P has an electromotive force (e.m.f.) of 1.5 V and power supply Q has an e.m.f. of 3.0V.
    Which statements about Q are correct when compared with P?
  19. The diagram shows a piece of metal resistance wire.
