Kinematics

Speed, velocity and acceleration Core Define speed and calculate speed from Plot and interpret a speed/time graph or a distance/time graph Recognise from the shape of a speed/time graph when a body is at rest moving with constant speed moving with changing speed Calculate the area under a speed/time graph to work out the distance [...]

Effects of Forces

Effects of Forces Core State that a force may produce a change in size and shape of a body Plot extension/load graphs and describe the associated experimental procedure Interprete extension/load graphs State Hooke’s Law and recall and use the expression Recognise the significance of the term ‘limit of proportionality’ for an extension/load graph Describe the [...]

Scalars and Vectors

Scalars and vectors Demonstrate an understanding of the difference between scalars and vectors and give common examples Add vectors by graphical representation to determine a resultant Determine graphically the resultant of two vectors Force is a vector.         Examples of vector are velocity, displacement and force. In addition to vectors, there is [...]

Turning Effects

Turning Effect Describe the moment of a force as a measure of its turning effect and give everyday examples Perform and describe an experiment (involving vertical forces) to show that there is no net moment on a body equilibrium Describe qualitatively the balancing of a beam about a pivot Apply the idea of opposing moments [...]

Conditions for Equilibrium

Conditions for Equilibrium State that, when there is no resultant force and no resultant turning effect, a system is in equilibrium Previously, we learnt that when there is no resultant force acting on a body, the body will remain at rest or continue its motion at a straight line. That is Newton’s First Law. What [...]

Centre of Mass

Centre of mass Perform and describe an experiment to determine the position of the centre of mass of a plane lamina Describe qualitatively the effect of the position of the centre of mass on the stability of simple objects         In other words, if a body is pivoted directly below its centre [...]

Mass and Weight

Mass and Weight Core Show familiarity with the idea of the mass of a body Demonstrate an understanding that mass is a property that ‘resists’ change in motion State that weight is a force Describe, and use the concept of weight as the effect of a gravitational field on a mass Demonstrate understanding that weights [...]

Density

Density 1.4 Density Describe an experiment to determine the density of a liquid and of a regularly sharped solid and make the necessary calculation Describe the determination of the density of an irregular shaped solid by the method of displacement, and make the necessary calculation     The SI unit of density is . Mathematically, [...]

Energy

1.6 (a) Energy Demonstrate an understanding that an object may have energy due to its motion or its position, and that energy may be transferred and stored. Give examples of energy in different forms, including kinetic, gravitational, chemical, strain, nuclear, internal, electrical, light and sound Recall and use the expression Give examples of conversion of [...]
