Key concepts of physics

  • Key concepts in physics - Edexcel

    Scientists often make measurements. These need to be stated with the units of the quantity being measured, and the accuracy of the measurements.

Motion and forces

  • Scalar and vector quantities - Edexcel

    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.

  • Motion - Edexcel

    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.

  • Newton's laws - Edexcel

    Resultant forces will cause acceleration, which can be described and calculated using Newton's laws of motion. Weight is caused by the gravitational effect of a planet attracting an object鈥檚 mass.

  • Momentum - Higher - Edexcel

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

  • Motion of vehicles - Edexcel

    Stopping vehicles as quickly as possible in an emergency is important but many factors affect this. The driver鈥檚 reactions and the road and vehicle conditions play a part, as well as mass and speed.

  • Sample exam questions - motions and forces - Edexcel

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

Conservation of energy

  • Changes in energy - Edexcel

    The amount of energy in a system can be changed. It cannot be created or destroyed but it can be transferred, dissipated or stored in different ways.

  • Efficiency - Edexcel

    Energy efficiency measures the proportion of energy which is wasted. The rate at which energy is wasted needs to be reduced and there are a number of ways to save energy, especially thermal energy.

  • Energy sources - Edexcel

    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.

  • Sample exam questions - conservation of energy - Edexcel

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

Waves

  • Properties of waves - Edexcel

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

  • Reflection and refraction - Edexcel

    All waves will reflect and refract in the right circumstances. The differences in transmission and absorption at material boundaries depend on the materials.

  • Sound and ultrasound - Edexcel

    Sound is caused by the vibration of particles, but not all vibrations can be heard as sound. Common ideas about sound come from the limited range of vibrations that human ears can detect.

  • Nuclear radiation - Edexcel

    With the wrong number of neutrons, nuclei can fall apart. A nucleus will regain stability by emitting alpha or beta particles and then 'cool down' by emitting gamma radiation.

  • Uses and dangers of radioactivity - Edexcel

    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.

  • Nuclear power - Edexcel

    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.
