Electromagnetic waves are transverse waves with a wide range of benefits and uses. Some of the waves also pose a risk and are hazardous to human tissues.

All objects are continually absorbing and emitting infrared radiation, which is essential for life on Earth.

Waves are one way in which energy may be transferred between stores. Both mechanical and electromagnetic waves will transfer energy but not matter.

Lenses are precisely shaped pieces of glass that have been developed and used in corrective glasses, telescopes, microscopes, binoculars, and magnifying glasses.

Understanding how to approach exam questions helps boost exam performance. Questions will include multiple choice, descriptions and explanations, using mathematical skills and extended writing.

Power is the rate at which energy is transferred. The amount of energy usefully transferred in a system determines how efficient that system is.

Every person, animal and device transfers energy. Much of the energy that is supplied by electricity must be generated from other energy stores - some are renewable but most are non-renewable.

The motion of charged particles causes electrical effects, small shocks, lightning and sparks. Electrical fields cause forces to act on charged particles.

Electrical current depends on resistance and potential difference. Different electrical components have different characteristics. These can be investigated using suitable circuits and apparatus.

Electrical current transfers energy around circuits. There are two different types of circuits – series and parallel.

Electrical current transfers energy around circuits. The power is the rate at which a circuit transfers energy.

Magnetism is caused by the fields that exist around magnets. These magnetic fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials.

Electromagnetism is the interaction between electric charges and magnetic fields, and describes how electricity and magnetism are linked. Electrons moving in a wire create a magnetic field around the wire, which can interact with external magnetic fields to produce a force.

Electromagnetic induction can create a potential difference. This potential difference causes a current, and the effect is used in electricity generation.

Forces arise from the interactions of two objects. They can be divided into two categories - contact forces and non-contact forces.

The movement of objects can be described using motion graphs and numerical values. These are both used to help in the design of faster and more efficient vehicles.

This interactive quiz is suitable for GCSE physics students studying scalar quantities, vector quantities and calculations involving forces.

This interactive quiz is suitable for GCSE physics students studying moments, moments and balanced objects, levers and gears.

Unbalanced forces on an object will change its motion. Ideas about force and momentum can be used to explain road safety measures.

This interactive quiz is suitable for GCSE physics students studying terminal velocity, Newton's first, second and third laws and braking.

This interactive quiz is suitable for GCSE physics students studying momentum calculations, conservation of momentum and force and momentum.

Energy stored in a moving object is called kinetic energy. As an object is raised above ground its gravitational potential energy increases. When a force moves an object work is done.

This interactive quiz is aimed at GCSE physics students studying types of energy store, energy transfers, energy dissipation, the conservation of energy and energy calculations.

The idea of the atom has developed over time. Each element has a number of different isotopes. When nuclei are unstable they may emit ionising radiation to become more stable.

People are exposed to sources of radiation in all aspects of everyday life. Radioactive sources can be very useful but need handling carefully to ensure safety.

The nuclei of atoms contain a large amount of energy. Releasing this energy would free the world from having to use fossil fuels. There are two methods of doing this: fission and fusion.

When energy is added to matter, its temperature will rise. The temperature rise will depend on the mass, which in turn depends on its density.

The particle model describes the arrangement of particles in solids, liquids and gases. It can be used to predict changes when matter is heated.

This interactive quiz is suitable for GCSE physics students studying states of matter, internal energy, energy and temperature, specific heat capacity and specific latent heat.

Visualise what happens when states of matter change with this interactive activity designed for the OCR 21st Century GCSE physics specification.

Forces are responsible for changing the motion of objects. If more than one force is present, the shape of an object can also be changed.

Every living thing on Earth is in balance with the pressure of the air or water around it. Pressure helps blood to move around the body and allows organisms to breathe.

This interactive quiz is suitable for GCSE physics students studying calculating pressure, pressure in a liquid and atmospheric pressure.

This interactive quiz is suitable for GCSE physics students studying particle motion, gas pressure and temperature, gas pressure and volume and changing gas pressure - Higher.

The Sun is our nearest star. It is a relatively small star when compared to other stars in the Universe. The Big Bang theory suggests how our Universe was created. The evidence for this is red-shift.

This interactive quiz is suitable for GCSE physics students studying the structure of the Solar System, the Sun, orbital motion and orbits and speed - Higher.

In general, scientists work out explanations based on repeatedly collecting and analysing data. The way in which scientists develop explanations is known as the scientific method.

It is important to process and present data in a way that makes it easy to analyse. It is also important to evaluate the quality of data before drawing a conclusion.

Data shows a correlation if the change in a factor is similar to the change in an outcome. Scientists must find a scientific explanation to conclude that a particular factor causes an outcome.

Considering the personal, social, economic, environmental and ethical issues is important when considering the impact of scientific advances to decide whether the benefits outweigh the risk.

Scientific investigations have several stages - planning, collecting data, analysing data and evaluation. It is important to understand how to carry out each stage of the investigation.

This interactive quiz is suitable for GCSE physics students studying planning, observing, analysing, evaluating an experiment and scientific equipment.
