Forces

Part of Combined Science

  • Forces

    • Scalar and vector quantities - AQA

      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.

    • and non- forces - AQA

      Forces are responsible for all the interactions between particles and objects. They can be divided into two categories: forces and non- forces.

    • Gravity - AQA

      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.

    • Forces and elasticity - AQA

      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.

    • Describing motion - AQA

      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.

    • Forces, acceleration and Newton's laws - AQA

      Falling objects eventually reach terminal velocity – where their resultant force is zero. Stopping distances depend on speed, mass, road surface and reaction time.

    • Momentum - Higher - AQA

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

    • Sample exam questions - forces - AQA

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