The physics of the universe appears to be dominated by the effects of four fundamental forces: gravity, electromagnetism, weak nuclear forces, and strong nuclear forces.  These forces control how matter, energy, space, and time interact to produce our physical world.  All other forces, such as the force you exert in standing up, are ultimately derived from these fundamental forces. We have direct daily experience with two of these forces: gravity and electromagnetism.  Consider, for example, the everyday sight of a person sitting on a chair.  The force holding the person on the chair is gravitational, and that gravitational force balances with material forces that “push up” to keep the individual in place.  These forces are the direct result of electromagnetic forces on the nanoscale.  On a larger stage, gravity holds the celestial bodies in their orbits, while we see the universe by the electromagnetic radiation (light, for example) with which it is filled.  The electromagnetic force also makes…

Gravity is the force that keeps us on the ground and understanding how gravity works is very important as it has a great influence on the upward and downward movement of objects. This free online course about gravity will explain Newton’s Second Law of Motion, the universal constant, which is used to work out the force of gravity throughout the universe. You will also learn what the effect of the earth's force of gravity, or little g as it is known, has on an object and why mass is not the same as weight. To fully understand gravity this course will take you step-by-step through the relevant formulas, showing you how to calculate velocity or distance based on time and then plot these changes so you will have a visual concept of what is happening. This course will be of great interest to students who are studying physics, chemistry, engineering, mathematics, and to students who wish to pursue a career in any of the sciences or engineering fields.<br />

Calculating change in motion is a very important concept to master in physics. When change happens in one dimension it is relatively easy to calculate the variable. However, change rarely happens in just one direction so you need to learn how to manage more than one variable. This free online physics course explains how to visually represent each change in a dimension as a vector so that it can be easily understood. You will learn how to add two vectors together and calculate all the relevant information for the resulting third vector. Working through various examples, including different elevations and inclines, you will learn how to solve for any variable through the use of the right-angled triangle and then use trigonometry and quadratic equations to calculate the relevant variables. This free online physics course will be of great interest to students who are studying physics, chemistry, engineering and mathematics and to any individual who wants to learn more about the movement of objects in two dimensions.<br />

In physics the study of movement and the motion of objects is called kinematics and is a branch of mechanics. The study of the motion of objects focuses on topics such as acceleration, position and velocity. In this free online course you will investigate the movement of objects by looking at the real-world application of kinematics. You will see how to answer interesting questions such as what distance does the Airbus A380 need for take-off, how long it takes for an FA-18 Hornet to take off from an aircraft carrier, and do race cars accelerate when cornering even if travelling at a constant speed. The course will walk you through a number of formulae, demystifying them by explaining and rearranging them in a clear and easy to understand way. This 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 the learner who wants to see how science can answer real-world questions.<br />

Motion, speed and time are three fundamental concepts in basic physics and they are important building blocks for understanding more advanced topics. This free online course introduces you to how distance, speed, time and mass are combined to give displacement, velocity, force and acceleration. Newton’s 3 Laws of Motion, which are the bedrock of much of our understanding of physics today, are also introduced and explained in a clear and concise manner. Along with explanations of the formulae used, a number of examples are worked through, giving a full understanding of the subject. References are also made as to how these formulae are used in real-world situations. By studying this course you will gain a clearer knowledge and understanding of important topics in basic physics.

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 free online 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 free online 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.<br />
