<p>This is a very useful set of 5 examples for calculating and combining uncertainties. The differentiated questions can be easily printed along with the solution pages when required. The uncertainty examples become more challenging as the students progress through the list: Area and Force (multiply), Velocity and Pressure (divide) and Resistivity (multiply and divide).</p>

<p>A great resource for combining uncertainties when adding, subtracting, multiplying and dividing. Can be used as an explanation, a starter test or a plenary. The power point pop-ups provide the solutions at each stage.</p>

<p>Using Conservation of Momentum diagrams, a vector equation is applied to an explosion using power point. Vector subtraction and vector addition are demonstrated. This is resource 5 in a series of examples on vector equations.</p>

<p>This is a Power Point on the Subtraction of Vectors which explains the process of Vector Subtraction in a step-by-step way. An introductory video link shows the near absence of relative velocity when two panes are approaching parallel runways. The process of subtracting vectors is explored using a right-angle triangle. Acute and obtuse angle triangles are then investigated. Six multiple choice examples are included throughout the package.</p>

<p>Using Conservation of Momentum diagrams, a vector equation is applied to a collision using power point. Vector subtraction and vector addition are demonstrated. This is resource 1 in a series of examples on vector equations.</p>

<p>A great resource for combining uncertainties when adding, subtracting, multiplying and dividing. Can be used as an explanation, a starter test or a plenary. The power point pop-ups provide the solutions at each stage.</p>

<p>Analysis of electrical circuits is used to calculate the resistance, potential difference, current and power for different parts of the arrangement. Three examples are provided each with increasing level of difficulty. The power point pop-ups show the questions and the solutions at each stage of the analysis. Can be teacher demonstrated and/or student investigation. The last example involves a battery of two cells with their poles reversed.</p>

<p>Great resource for demonstrating the ray diagram construction for the image of an object in a plane mirror, step by step, using Power Point.</p>

<p>Students are invited to read off values from a straight line graph in order to state and calculate the intercept and gradient and to estimate their uncertainties.</p>

<p>Using Conservation of Momentum diagrams, a vector equation is applied to a collision using power point. Vector subtraction and vector addition are demonstrated. This is resource 2 in a series of examples on vector equations.</p>

<p>Using Conservation of Momentum diagrams, a vector equation is applied to an explosion. Vector subtraction and vector addition are demonstrated. This is resource 4 in a series of examples on vector equations.</p>

<p>Students are invited to read off values from a straight line graph in order to state and calculate the intercept and gradient and to estimate their uncertainties.</p>

<p>This is a Power Point on the Addition of Vectors which explains the process of Vector addition in a step by step way. We start with a very short video link as a plane lands in strong cross winds. The process of adding vectors is then explored using calculations and then scale diagrams for right angle triangles. Acute and obtuse angle triangles are then finally investigated. Lesson objectives are included.</p>
