Learning Outcomes:

● show an understanding that a force can be a contact or non-contact force. e.g., contact force (frictional force); non-contact force (magnetic force; gravitational force)

● recognise that the interactions between two or more objects, result in a transfer of energy which can/may cause changes (by application of force) to the

- state of rest or motion of a body

- size and/or shape of a body

- turning effects in objects (e.g., spanners, levers to open tins)

- pressure on objects

● *show an appreciation of some daily life phenomena associated with

- pressure (e.g., high heel shoes, cutting edge of a knife),

- atmospheric pressure (e.g., use of suction cups, drinking from straws) and

- pressure due to liquid (e.g., submarines)

● state the SI unit of *work and energy as the joule

● *identify that work is done is an example of energy transfer that occurs when an object moves in the direction of a force

● recognise that energy cannot be created nor destroyed, it is conserved when it is transferred (from one object to another) and/or converted (from one form to another)

● measure force, using newton as the SI unit

● compare mass and weight

● *investigate pressure using the formula, pressure = force/area

● infer that energy can be converted from one form to another

● show an appreciation of the uses of various sources of energy (e.g. fossil fuels, solar, hydro-electric, wind energy, geothermal energy, biofuels and nuclear energy) and their impact on the environment

● show curiosity about the destructive power of forces in nature (e.g., tsunamis, volcanic eruptions, earthquakes, tropical cyclones)
