Topic 1 – Key concepts of physics
A kettle takes 0.25 hours to boil dry. How many seconds is this?
Practise Topic 1 – Key concepts of physicsTopic 10 – Electricity and circuits
A battery-powered electric toothbrush is switched on. Describe the main energy transfer that occurs in the toothbrush's motor.
Practise Topic 10 – Electricity and circuitsTopic 11 – Static electricity
A paint sprayer gives paint droplets an electric charge while the metal object being painted is earthed. Why does this make the painting more efficient?
Practise Topic 11 – Static electricityTopic 12 – Magnetism and the motor effect
A student wants to make the magnetic field at a fixed point near a straight wire stronger. Which change would achieve this?
Practise Topic 12 – Magnetism and the motor effectTopic 13 – Electromagnetic induction
A straight wire is moved between the poles of a magnet so that it cuts through the magnetic field lines. What happens in the wire?
Practise Topic 13 – Electromagnetic inductionTopic 14 – Particle model
A metal cube has a side length of 0.2 m and a mass of 64 kg. What is the density of the metal?
Practise Topic 14 – Particle modelTopic 15 – Forces and matter
A person stands on soft snow wearing ordinary shoes and sinks in. The same person then wears wide snowshoes and stays on the surface. What is the reason for the change?
Practise Topic 15 – Forces and matterTopic 2 – Motion and forces
A satellite orbits the Earth in a circle. What provides the centripetal force that keeps it in orbit, and in which direction does this force act?
Practise Topic 2 – Motion and forcesTopic 3 – Conservation of energy
A bicycle chain becomes warm as the bicycle is pedalled because friction transfers energy to the surroundings. Which change would reduce this unwanted energy transfer?
Practise Topic 3 – Conservation of energyTopic 4 – Waves
A student watches a wave travel across a pond and says the water must be moving across the pond. Which observation would best test this claim?
Practise Topic 4 – WavesTopic 5 – Light and the electromagnetic spectrum
A body stays at a constant temperature. What must be true about the power it radiates and absorbs?
Practise Topic 5 – Light and the electromagnetic spectrumTopic 6 – Radioactivity
A sample contains 500 g of a radioactive isotope with a half-life of 10 years. What mass of the isotope remains after 30 years?
Practise Topic 6 – RadioactivityTopic 7 – Astronomy
An artificial satellite is launched into a low orbit close to the Earth's surface. Compared with a satellite in a much higher orbit, how does the low-orbit satellite move?
Practise Topic 7 – AstronomyTopic 8 – Energy – forces doing work
A fan is supplied with 500 J of energy and transfers 350 J as useful kinetic energy to the air. What is the efficiency of the fan?
Practise Topic 8 – Energy – forces doing workTopic 9 – Forces and their effects
