Two-dimensional motion

This course is a part of AP®︎ Physics 1, a 12-course Topic series from Khan Academy.

Now that we understand velocity and acceleration well in one-dimension, we can explore scenarios that are even more fun. With a little bit of trigonometry, we can think about whether a baseball can clear the "green monster" at Fenway Park.

This course contains 5 segments:

Introduction to vectors and two-dimensional motion

We'll review how to add, subtract, and break down vectors graphically. These skills will be helpful for analyzing motion in two-dimensions.

Analyzing vectors using trigonometry

We'll review how to analyze vectors using trigonometry. You might find it helpful to brush up on sine and cosine functions.

Graphs of projectile motion

We'll use graphs to analyze projectile motion in the horizontal and vertical directions.

Horizontally launched projectiles

This lesson builds on one and two-dimensional kinematics to answer questions about horizontally launched objects, such as how long and far something can travel.

Projectiles launched at an angle

This lesson tackles a fundamental question, how do we launch things as far as possible? We'll build our intuition for finding optimal launch angles with a little bit of trig.
