Centre of Mass - A Level Physics (OCR A)

Dynamics & Statics - A Level Physics (OCR A)

Unit: Dynamics & Statics Number of lessons: 12 This bundle includes all twelve lessons in my unit Dynamics & Statics (referred to as Forces in Action in the specification). It is specifically linked to the OCR Physics A Specification, but should apply to most A Level Physics courses. The lessons cover the following points: 1) Types of forces 2) Definition of the newton 3) Force and acceleration (F=ma) 4) Weight (W=mg) 5) First condition of equilibrium (in terms of net (resultant) force) 6) Closed vector triangle of forces 7) Practical investigation of coplanar forces 8) Drag and terminal velocity 9) Centre of mass and centre of gravity 10) Experimental determination of centre of gravity (for a thin sheet) 11) Turning forces (moment/torque) 12) Principle of moments 13) Second condition of equilibrium (in terms of net (resultant) moment) 14) Practical application of principle of moments 15) Density 16) Experimental determination of density (regular and irregular solids) 17) Use of vernier calipers 18) Archimedes' principle 19) Pressure There are detailed teacher notes in the 'Notes' section of each slide, including answers where required. My first unit of lessons (Physical Quantities & Units) is available free of charge for you to see the style I employ.
