Physics - Motion, Speed and Time
This course will first introduce you to the physics of motion, speed, and time. You will study scalars, which are quantities that are fully described by a magnitude or numerical value, while vectors are quantities that are fully described by both a magnitude and a direction. You will learn how to calculate average velocity or speed and how to solve for time. This course will also teach you how to derive displacement from time and velocity.
Acceleration is an object's change of velocity with respect to time. This course will discuss acceleration with respect to velocity. You will study Newton's Three Laws of Motion, which indicate that first, every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. Second, force equals mass times acceleration, and third, for every action there is an equal and opposite reaction.
The study of physics can help you strengthen your quantitative reasoning and problem-solving skills, which are highly valuable in several areas beyond physics. This course will teach you how things work from first principles to help you gain a clearer knowledge and understanding of important topics in basic physics.

Physics - Introduction to Motion in Two Dimensions
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 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 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.1-2 Hour50 Points
Physics - Advanced Motion in Two Dimensions
Using vectors to study motion is a fundamental skill to have when studying physics. Vector quantities used to describe the physical world include displacement, velocity, acceleration, and force.
In this physics course the standard way to represent vectors and their axes as well as unit vector notation are explained in a clear and step-by-step manner. Examples show how to work out the angle or distance necessary to get the desired displacement. Using two known variables you will learn how to work through the process of calculating the remaining value, such as time in air or horizontal displacement using a variety of techniques.
This physics 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, and even the sportsperson who wants to plan for a specific outcome when hitting a golf ball or batting a ball.1-2 Hour50 Points
Physics - Gravity
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 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.1-2 Hour50 Points
Physics - Kinematics through Practical Examples
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 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.1-2 Hour50 Points
Physics - Normal and Contact Forces
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.1-2 Hour50 Points
