Unit: Motion in a plane

We'll review how to add, subtract, and break down vectors graphically. These skills will be helpful for analyzing motion in two-dimensions.
We'll review how to analyze vectors using trigonometry. You might find it helpful to brush up on sine and cosine functions.
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.
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.
Let's escape from the binds of one-dimension (where we were forced to launch things straight up) and start launching at angles. With a little bit of trig (might want to review sin and cos) we'll be figuring out just how long and far something can travel.
Till now we have been throwing projectile on a horizontal surface, let's throw it on an incline now.
Let's learn how to solve problems involving relative velocity and frames of reference when the motion happens on a plane.

About this unit

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.
