HOME LEARNING: A-Level OCR A Mechanics

A PowerPoint with lots of topics covered. For some of the harder stuff (read toward the end of the below list) has comprehensive explanation and a worked example for you to attempt. It’s very much a work in progress but I thought I would upload it with all the Coronavirus stuff going on.

It may even provide some nice templates for you to use in your lessons :)

It covers the following:

• An Intro to i and j components of a 2-D vector

• Defining Magnitude and Direction

• Resultant forces in 2-D

• Resolving forces in 2-D

• Resolving forces in 2-D using Trigonometry (Explanation)

• Resolving forces in 2-D using trigonometry (Practice)

• Resolving Forces given a vector’s magnitude and direction

• Resultant Force of Two Contributing Forces

• Resultant Force of Three Contributing Forces

• Newton’s Second Law

• Block on a Slope

• Block on a Rough Slope (Friction)

• Two Masses on a Pulley (Examples and Practice)

• Two Masses on a Pulley: Mass on a Rough Slope (Examples and Practice)

• Moments

• Moments and Uniform Rods (Examples and Practice)

• Moments and Sloped Uniform Rods (Examples and Practice)

• Moments - Equilibrium (Examples and Practice)

Big ups Gregg Wallace!
