Mechanics is the area of mathematics that studies the relationships between motion, forces and energy. While mechanics is often taught as a separate topic, the mathematics involved arises throughout the subject. As we develop resources related to mechanics, they will be placed at the appropriate station, for example, work with velocity-time graphs in Speed vs velocity appears at the Introducing Calculus station and Thinking constantly, which aims to improve studentsâ€™ understanding of the link between acceleration, velocity and displacement functions and their graphs, appears at Calculus meets Functions.
