Free course


This free course is concerned with moving objects, that is, dynamics. Section 1 introduces concepts like position, velocity and acceleration, which describe the way an object moves. Section 2 discusses Newton’s laws of motion, which predict the motion of an object when the forces acting on it are known. Section 3 shows how Newton’s second law of motion can be used to predict the motion of objects. Section 4 concerns modelling some of the forces that occur in nature, which enables more realistic situations to be analysed. Section 5 looks at motion in more than one dimension.

Course learning outcomes

After studying this course, you should be able to:

  • understand and use basic terms for the description of the motion of particles, vector functions and the fundamental laws of Newtonian mechanics
  • solve mechanics problems in one dimension that involve one or more of the forces of gravity, friction and air resistance
  • understand the concept of terminal speed, and use it in solving mechanics problems in one dimension
  • apply Newton’s second law in vector form to problems in more than one dimension
  • solve problems relating to the motion of a projectile in the absence of air resistance.
