Physics - Advanced Motion in Two Dimensions

Gain better insight into advanced motion using two-dimensional vectors, optimal angle for a projectile, and more.

Free Course
This free online physics course will teach you about advanced motion in two dimensions. You will study the standard way to represent vectors and their axes including unit vector notation. You will learn how to work out the angle or distance necessary to get the desired displacement as well as use two known variables to work through the process of calculating the remaining value such as time in the air or horizontal displacement.

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. Check out this course and learn more about advanced motion in two dimensions today.
