CIE IGCSE Physics Topic 1 REVISION (General Physics)

This is an engaging REVISION lesson which uses a range of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content within topic 1 (General Physics) of the CIE IGCSE Physics (0625) specification. The lesson covers the content in both the core and supplement sections of the specification and therefore can be used with students who will be taking the extended papers as well as the core papers.

The specification points that are covered in this revision lesson include:

CORE

• Define speed and calculate average speed from total distance divided by total time
• 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 at a constant speed or changing speed
• Calculate the area under a speed-time graph to work out the distance travelled for motion with constant acceleration
• Show familiarity with the idea of the mass of a body
• State that weight is a gravitational force
• Distinguish between mass and weight
• Recall and use the equation W = mg
• Recall and use the equation density = mass divided by volume
• Understand friction as the force between two surfaces which impedes motion and results in heating
• Calculate moment using the product force × perpendicular distance from the pivot
• Identify changes in kinetic, gravitational potential, chemical, elastic (strain), nuclear and internal energy that have occurred as a result of an event or process
• Recognise that energy is transferred during events and processes, including examples of transfer by forces (mechanical working), by electrical currents (electrical working), by heating and by waves
• Apply the principle of conservation of energy to simple examples
• Describe how electricity or other useful forms of energy may be obtained from a range of sources
• Show a qualitative understanding of efficiency
• Demonstrate understanding that work done = energy transferred
• Relate (without calculation) power to work done and time taken, using appropriate examples

SUPPLEMENT

• Distinguish between speed and velocity
• Define and calculate acceleration
• Understand deceleration as a negative acceleration
• Describe, and use the concept of, weight as the effect of a gravitational field on a mass
• State Hooke’s Law and recall and use the expression F = k x, where k is the spring constant
• Apply the principle of moments to different situations
• Understand that vectors have a magnitude and direction

The students will thoroughly enjoy the range of activities, which include quiz competitions such as “Are you the KING of the KINGDOMS” where they have to name the kingdoms involved based on a feature whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual IGCSE exam
