Lesson introducing the use of forces and turning effects like levers, including moments - includes practice questions for students. Also suitable to higher KS3 classes.
Ideal for Cambridge iGCSE P3
Lesson 1/2
Developing: Describe the moment of a force as a measure of its turning effect and give everyday examples.
Secure: Understand that increasing force or distance from the pivot increases the moment of a force.
Exceeding: Recognise that, when there is no resultant force and no resultant turning effect, a system is in equilibrium.
Lesson 2/2
Developing: Calculate clockwise and anti-clockwise moments using the formula: moment = force x perpendicular distance from pivot
Secure: Apply the principle of moments to different situations.
Exceeding: Apply the principle of moments to the balancing of a beam or pivot.
