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.

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.

Matter is made up of atoms about 0.1 nm in size. Atoms and molecules are arranged differently in solids, liquids and gases. Density is calculated from mass divided by volume.

Changes in temperature or physical state are caused by transfers of energy. Specific heat capacity determines the energy needed to change temperature, and specific latent heat is the energy needed to change state.

Want to know what happens when the states of matter change? Find out with this interactive activity designed for the GCSE OCR Gateway physics specification.

Gases and liquids exert pressure on objects and the walls of their containers due to collisions. The greater the force and frequency of these collisions, the greater the pressure.

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.

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

Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors. Scalar and vector quantities are treated differently in calculations.

Speed and velocity refer to the motion of an object. Distance-time and velocity-time graphs can be a useful way of analysing motion.

Isaac Newton’s laws surrounding forces were formulated hundreds of years ago, but are still used today - they help to describe the relationship between a body and the forces that act upon it.

Momentum can be thought of as the product of mass and velocity. Momentum helps explain some of the most important interactions in nature.

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

Gravity is one of the most important forces in the universe. An object with mass in a gravitational field experiences a force known as weight.

Turning forces are found in many everyday situations and are essential for machines to function. Levers and gears make use of these turning forces to aid movement.

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.

Electric current is caused by moving electric charges. The effects of charge and electric fields can be investigated by looking at the forces they exert on conductors and insulators.

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

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

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 voltage. This voltage can make current flow, and the effect is used in electricity generation.

Transformers use electromagnetic induction to change the potential difference of alternating currents. Potential difference and current changes can be calculated, as the power transfer is constant.

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

At a boundary, waves are reflected, refracted, or absorbed. Waves, such as ultrasound, can be used in medicine and other industries.

Electromagnetic waves are transverse waves with a wide range of properties and uses. Some of the waves are also hazardous to human body tissues.

What are lenses? In this GCSE physics study guide, you will learn that lenses are precisely shaped pieces of glass that have been developed and used in corrective glasses, telescopes, microscopes, binoculars, and magnifying glasses.

Colour and the nature of images depend on how visible light is reflected, absorbed or transmitted when it interacts with materials.

Unstable atomic nuclei emit radiation. Each type of radiation has different properties and interacts with matter in varying ways. Radioactive decay is random but can be measured.

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.

Energy can be described as being in different 'stores'. It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

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.

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

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.

Everyday, people and vehicles travel at different speeds and are exposed to large accelerations and forces.

Much of the energy used on Earth is supplied by electricity which must be generated from other energy stores – some are renewable but most are non-renewable.

The electricity used in homes, shops, hospitals and factories has to be transported large distances from power stations without energy being lost to the surroundings.

Theories about the Universe's development, such as the Big Bang theory, are based on astronomical observations such as red-shift and cosmic microwave background radiation.

The Sun is a relatively small star when compared to other stars in the Universe. The Solar System contains the Sun and everything that orbits it.

All objects emit and absorb electromagnetic radiation, which is essential for life on Earth. Waves can be used to probe inside the Earth to examine its internal structure.

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

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.
