Description
Statics deal with objects at rest and ones that are moving with constant velocity. In this case, the forces acting over the objects are at equilibrium. Edexcel’s latest Scheme of Work document now includes many links for the use of technology as well as all the very useful notes for teachers. A link from the Mechanics notes led to these CG50 Mechanics resources. Casio CG50 Mechanics Resources The assessment is structured in two sections of approximately 50 marks each: pure mathematics and mechanics. Each section has a gradient of difficulty throughout the section and consists of a mix of short and long questions.
In the diagram above, the vector r has magnitude r and direction j to the x-axis. Using basic trigonometry, we can calculate that the component of r in the direction of the x-axis is rcos j. The component in the direction of the y-axis is rsin j. Therefore r = rcos j i + rsin j j. In addition to the resources listed below, I recommend Integral(school login required) which provides topic notes, worksheets, activities and assessments. Also, the National STEM Centre eLibrary has a good range of mechanics resources, including the excellent Mechanics in Action investigations.

A Level Pure Mathematics
The assessment has a gradient of difficulty throughout the paper and consists of a mix of short and long questions. Assumptions help reduce the complexities of real-life applications of mechanics by ignoring certain variables.
Therefore, if no other forces act on the bodies (in the direction of collision), then the total momentum of the two bodies will be unchanged. Hence the total momentum before collision in a particular direction = total momentum after in a particular direction. Kinematics is an area of study that focuses on the movement of objects, disregarding the forces that cause the movements. Students must take both components to be awarded the OCR AS Level in Mathematics A. Content overview Hammer vs feather - physics on the moon- get students to do their own calculations of the acceleration of gravity. They can estimate the height from where they are dropped, they can all time it with their phones, and they know initial velocity is zero(1.5 minutes) A unit vector is a vector which has a magnitude of 1. There are three important unit vectors which are commonly used and these are the vectors in the direction of the x, y and z-axes. The unit vector in the direction of the x-axis is i, the unit vector in the direction of the y-axis is j and the unit vector in the direction of the z-axis is k.Since the vectors are given in i, j form, we can easily calculate the resultant. 3 i + j - 5 i + j = -2 i + 2 j
If two vectors are added together, the resultantis found by placing the vectors to be added end to end. If the vectors are given in unit vector form, you simply add together the i, j and k values. Edexcel’s GeoGebra resources include a small number for Mechanics at A level, and more for Further Maths. Mathematics Resources align to the syllabus they support, and have been through a detailed quality assurance process. The assessment is structured in two sections: approximately 50 marks of pure mathematics and approximately 25 marks of mechanics. Each section has a gradient of difficulty throughout the section and consists of a mix of short and long questions. We have the following scenario (a ball of mass 3kg is moving to the right with velocity 3m/s and a ball of mass 1kg is moving to the left with velocity 2m/s):The impulseof a force (also measured in N s) is equal to the change in momentum of a body which a force causes. This is also equal to the magnitude of the force multiplied by the length of time the force is applied. These overarching themes should be applied, along with associated mathematical thinking and understanding, across the whole of the detailed content in the specification: Cambridge International AS & A Level Mathematics: Cambridge Elevate Teacher's Resource contains detailed lesson notes for each section of all five coursebooks in this series as well as additional guidance on the Explore activities within the books, PowerPoint slides with links to further resources and answers to all coursebook and practice book exercises. Letters used to represent vectors should always be underlined or in bold type. For example, the velocity of an object may be represented by v. Since this is a vector quantity, it is in bold type. Small case letters are usually used to represent vectors.
