Edexcel’s GeoGebra resources include a small number for Mechanics at A level, and more for Further Maths. Mathematics

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) The assessment has a gradient of difficulty throughout the paper and consists of a mix of short and long questions. Mass is one significant variable to be considered when exploring the effects of motion in objects, and mass is a central variable in Newton's second law. 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): 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.A vector quantity has both magnitude and direction. Acceleration, velocity, force and displacement are all examples of vector quantities. A scalar quantity has magnitude, so the direction is not important, (examples include speed, time and distance). A scalar can also have sign (such as work done and charge). Students must take both components to be awarded the OCR AS Level in Mathematics A. Content overview These overarching themes should be applied, along with associated mathematical thinking and understanding, across the whole of the detailed content in the specification: 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. 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.

This text builds fluency in algebraic manipulation and introduces new areas including 3D vectors, differential equations and complex numbers. Extensive and varied practice sections build the key mathematical skills along with a focus on mathematics in life and work. Online answer key available. Momentum is measured in N s. Note that momentum is a vector quantity, in other words the direction is important. Supports Paper 4 of the Cambridge International AS & A Level Mathematics syllabus for examination from 2020 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 Resources align to the syllabus they support, and have been through a detailed quality assurance process.

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]. 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. 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. 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. 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

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.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.
