Fig. 1.1 shows the speed–time graph for a cyclist beginning a race. The motion of the cyclist changes at points A, B and C. The y-axis is speed in m/s (0 to 20), the x-axis is…

State the principle of conservation of energy.

A platform rests on a pivot as shown in Fig. 3.1. A diver sits at a distance of 1.8 m from the pivot. The weight of the diver is 1100 N. A spring is attached on the other side of…

A student holds a pile of books. The mass of the books is 3.2 kg. Calculate the weight of the books.

Fig. 5.1 shows a tidal turbine fixed to the seabed by a cable, below sea level, with water flowing past it. A tidal turbine generates electricity from the energy stored in tides.…

Fig. 6.1 shows a cold drink in a thermal jug. The jug reduces thermal energy transfer from the surroundings to the drink. It has a hinged lid, ice, a vacuum (empty space), plastic…

A student can hear trains passing her house. Describe the motion that a sound wave gives to air particles.

In Fig. 8.1, each diagram illustrates a wave property. The top diagram shows waves passing a barrier and spreading; the bottom diagram shows a ray of red light entering glass. The…

Fig. 9.1 shows an electric water heater connected to the mains electrical supply, with a plastic cover. Fig. 9.2 shows the electrical safety label for the heater: 230 V (volts),…

Different materials have differing magnetic properties. State the name of a material that is suitable for a temporary magnet.

Fig. 11.1 represents all the particles in a beryllium atom (showing 4 electrons, 4 protons and 5 neutrons; the key lists electrons, protons and a third type to be named). The…

There are eight planets in our Solar System. Table 12.1 shows the names of some of the planets in order of distance from the Sun: Mercury, ..., Jupiter, ..., Neptune (in order of…
