Newton’s Third Law is fundamental, but it is surprisingly easy for students to recite the Law without understanding the physics.
This resource is designed to change that.
Unique to bedrock physics (at the time of writing), you get an interactive HTML page that allows students to see and investigate the physics for themselves.
###Powerpoint lesson
to take students from first principles to exam application.
*Smart Start / Do Now - activate prior knowledge and get students thinking from the outset
*Clear explanations - build the key ideas step by step, with a focus on genuine understanding
*Misconceptions put right - confront the common ways students misunderstand Newton’s First Law
*Exam-style questions - apply the ideas in the way students will encounter them at GCSE.
*22 slides
###Interactive HTML
*just double click the file to open in a browser
*Distinguish between force pairs and balanced forces
*Gain clarity about drawing force diagrams
*Reinforcement through many real world scenarios
*Ideal for teacher demonstration, paired work or independent learning. Makes great quality cover lesson work too.
*Runs directly in a web browser, on smartboard, ipads, laptops, no internet required.
The webpage includes
A recap of types of contact and non-contact forces (sorting activity)
A step-by-step explanation of every concept hidden in Newton’s 3rd Law
many real world examples
Detailed explanations that tackle the common problems when trying to consider forces on one, two or three objects.
Two simulations that allow students to ‘freeze’ the interactions between objects, and see the force vectors that are acting at any given moment in time, or watch how the vectors change over time when they unfreeze the motion.
Lots more practice questions.
Two more games, based on equal and opposite forces between two objects, to consolidate the learning objectives.
