A-Level Maths for Edexcel - Mechanics 1: Student Book

Product Information

Kinematics is an area of study that focuses on the movement of objects, disregarding the forces that cause the movements. 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. Please send additional resource recommendations to [email protected]. Momentum is measured in N s. Note that momentum is a vector quantity, in other words the direction is important. The assessment is structured in two sections of approximately 50 marks each: pure mathematics and statistics. Each section has a gradient of difficulty throughout the section and consists of a mix of short and long questions. Some questions will be set on the pre-release data set.

When you select Answers and full worked solutions for any book, see Edexcel Appliedfor example, as well as the pdf document of questions with full worked solutions for the ‘Target your revision’, ‘Exam-style’ and ‘Review’ questions, you will find test yourself multiple-choice questions for each section. 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. 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.

Suppose we are told that after the collision, the ball of mass 1kg moves away with velocity 2m/s, then we can use the principle of conservation of momentum to determine the velocity of the other ball after the collision.

Although the following questions are predominantly from the OCR, OCR MEI and Edexcel exam boards, they are suitable practice for all UK A Level Maths qualifications unless otherwise stated. SectionStudents must take both components to be awarded the OCR AS Level in Mathematics A. Content overview
