# Unit 2: Motion in a plane (Hindi)

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.

## Introduction to vectors and two-dimensional motion (Hindi)

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 (Hindi)

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 (Hindi)

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

## Horizontally launched projectiles (Hindi)

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 (Hindi)

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.

## Projectiles launched from/to a height (Hindi)

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.

## Projectile on an incline (Hindi)

Till now we have been throwing projectile on a horizontal surface, let's throw it on an incline now.

## Relative motion in 2D (Hindi)

Let's learn how to solve problems involving relative velocity and frames of reference when the motion happens on a plane.

## Uniform circular motion introduction (Hindi)

In this lesson, we will learn how to describe the motion of objects moving in a circle using angular motion variables such as angular velocity and angular displacement.

## Centripetal acceleration (Hindi)

Is something moving in a circle at a constant speed accelerating? If so, in what direction? In this lesson, we'll consider centripetal acceleration in more detail.
