Turning Effect of Forces for iGCSE / GCE "O" Level Physics

Turning Effect of Forces for iGCSE / GCE "O" Level Physics free download

Learn each concept in under 10 minutes

If you are a student taking the Cambridge iGCSE / GCE “O” Level Physics examination, this is the course that will help you master the topic on the Moment of a Force and Stability. 

This course is carefully curated to help students prepare and score well for their Physics examination .  The course has been designed to make the learning process simple, fast and effective.

Every lesson consists of a short video that explains the concept with animated illustrations using everyday-life examples. At various learning milestones, quizzes with questions of gradual difficulty levels are provided to enable students to test their understanding and reinforce their learning. Throughout the course, students will be given exam preparation tips, advised on commonly made mistakes and misconceptions and taught the skills of how to correctly answer examination questions. By the end of the course, students will be well equipped with the knowledge required for Cambridge iGCSE / GCE “O” Level Physics examination.

What you will learn

• describe the moment of a force about a pivot in terms of its turning effect and relate this to everyday examples

• apply the relationship moment of a force (or torque) = force × perpendicular distance from the pivot to solve problems

• understand that the principle of moments for a body applies to they body in rotational equilibrium (not turning)  and understand that a body in equilibrium also has to satisfy the criteria that resultant force is zero

• apply the principle of moments to calculate unknown force or distance

• apply the concept of the moment of a force to check if a system will remain balanced or will start to rotate

• identify the perpendicular distances in levers and systems with rotating force

• recognise that forces passing through the pivot has no turning effect

• show an understanding that the weight of a body may be taken as acting at a single point known as its centre of gravity

• describe qualitatively the effect of the position of the centre of gravity and how the weight of an object has a turning effect that will affect its stability.
