Courses in this Learning Path
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 the 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 course begins by discussing the change in motion in two dimensions. You will learn to visualize vectors in 2 dimensions and look into projectile at an angle and projectile on an Incline.
You will then study the different ways to determine the time in the air. This course will also discuss launching and landing on different elevations, total displacement for a projectile, total final velocity for a projectile, and correction to total final velocity for a projectile. You will look at a sample computation which will show you that the horizontal displacement is the amount of time in the air multiplied by the constant horizontal velocity.
Upon completion of this course, you will gain a better understanding on how to break movement into its components, use the right-angled triangle and trigonometry to solve problems, learn how vectors plot against two dimensions, solve for one dimension using the other, solve to different elevations, and calculate variables for projectile on an incline.

Physics - Advanced Motion in Two Dimensions
This course begins by giving you an overview of advanced motion using two-dimensional vector. 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. You will study unit vectors and engineering notation as well as look into the famous Fenway Park in Boston and figure out what is the velocity needed for a batter to hit the ball, make it cross the Green Monster, and hit home run.
You will then study the optimal angle for a projectile. You will learn that a vector is something that has a magnitude and direction while speed is just the magnitude of the velocity. You will learn how to solve for the vertical velocity or the vertical component of the velocity, the horizontal speed or the horizontal component, the magnitude of the horizontal component, and the optimal angle and distance using a bit of calculus.
It is very interesting to know that you can plan for a specific outcome when hitting a golf ball or batting a ball. Upon completion of this course, you will have a better understanding of what a unit vector is used for and be able to break down a problem into individual components. You will also learn how to solve for any variable using trigonometry as well as for optimal height or distance.

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
This course begins by introducing you to the concept of kinematics which is the study of the movement and motion of objects. You will look at practical examples to help you gain a clear understanding of the kinematics principles and the importance of physics in solving real-world problems. You will learn how to calculate practical examples and problems related to movement, work through examples using formulas, calculate acceleration, velocity, displacement of a body, and use velocity-time graph to visualize data.
You will then learn that race cars accelerate when cornering even if traveling at a constant speed as there is a change in direction. This course will also show you that the Airbus A380 has a takeoff velocity of 280 km/hour and that an FA-18 Hornet has a take-off speed of 260 km/hour from an aircraft carrier and needs an aircraft length of 80 meters. You will also learn that distance is the area under velocity-time line and that displacement can be calculated as the area under the curve in a velocity-time graph.
In physics, the study of movement and the motion of objects is called kinematics which is a branch of mechanics. The study of the motion of objects focuses on topics such as acceleration, position, and velocity. Upon the completion of this course, you will better understand the movement of objects by looking at the real-world application of kinematics.

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
