Forces and Motion

This 10-lesson unit engages students in investigations to understand Newton’s second law of motion. Students start the unit by discussing vehicle collisions and continue by performing activities to explore the driving question - ‘How can I design a car which is safer for passengers during a collision?’ The content focus of this unit is on understanding the relations between the net force on an object, its mass, and its acceleration. The unit includes several opportunities for students to construct, test, revise and share their models to explain the investigated phenomena, while performing experiments and using computer simulations.

• Develop inquiry and modelling skills for scientific explanations and analyse data to assess the explanations 

• Gain an understanding of Newton’s second law of motion

• Identify relationship between acceleration, mass, and force

This unit has a creativity and critical thinking focus:

• Design, evaluate, and refine a personally novel solution (device) to a scientific problem

• Generate unusual ideas to propose and model scientific solutions

Opportunities to adapt, Extend and Enrich

• This unit is the first in a sequence of three high school Physics units. The other units focus on magnetic fields and electric motors.

• This could be extended by giving examples that explore Newton’s laws of motion in cricket or other sports. See, for example, this video on American Football https://www.youtube.com/watch?v=qu_P4lbmV_I
