Designed to teach KS4 about how to calculate resultant forces when the forces are non-collinear. Gives examples of when forces which occur in such a way. Animated guide to drawing a parallelogram as a worked example, colour coded for ease of viewing. Gives students past exam style questions for practise

Designed for year 10 and 11 for the new AQA specification. Animated powerpoint designed to lead students through calculating resultant forces using right angle triangles. Introduction is a recap on resultant forces. Allows students to become confident with drawing ‘triangles of forces’ for diagonal resultant forces (animated answers to show the relevant forces) Shows how ‘alternate angles’ are used to help calculate angles. Worked examples of SOHCAHTOA to calculate angles and unknown forces Plenary is a worked exam style question.

Designed to be delivered to KS4 groups. This continues from discussing parallel forces and explains to students how to calculate what forces occur when an object is on a slope. Using the example of a trolley on a hill the students are lead step by step through the different forces and how to draw a triangle of forces. From this they are given worked examples and then a differentiated task to determine confidence levels. Ends with a dicussion about forces acting in different directions.
