Understanding the concept of force and the effects various forces have on objects are very important topics in physics. For example, when you try to move a heavy object it takes more effort to get it moving than to keep it moving because of gravity and the different types of friction involved.

In this physics course you will learn more about the force of gravity and its counterpart the normal force, and why some objects do not move even when they are on a slope. The force of friction is also discussed, including static and kinetic types, and as friction is dependent on types of the materials involved the course also looks at the coefficient of static friction relative to kinetic friction. Examples of each type of force are worked through giving the learner a clear insight into how forces work together and how to calculate their respective values.

This physics course will be of great interest to students who are studying physics, chemistry, engineering and mathematics, to students who wish to pursue a career in any of the sciences or engineering fields, and to anybody wanting to understand the dynamics of moving objects on specific surfaces.

Upon the completion of this course you will be able to: - Demonstrate an understanding of what normal and contact force are; - Calculate normal force; - Break down force of gravity into its components; - Describe static an kinetic friction; - and solve for static and kinetic friction.
