Physics News

Motion quantities can be divided into two categories - vectors and scalars. Our focus now will be on vectors - a quantity that describes both magnitude and direction. The emphasis of vectors is to understand some fundamentals about vectors and to apply the fundamentals in order to understand motion and forces that occur in two dimensions. The most common example of an object that is moving in two dimensions is a projectile. A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.


THIS WEEK (10/21- 10/25):

This week we will begin our focus on vector components. When analyzing motion, it is often necessary to utilize the individual x and y components. First we will draw vectors correctly on the coordinate plane and find the resultant vector with direction. Then, we will determine what the x and y components are when given a resultant vector. SOH-CAH-TOA and the Pythagorean Theorem will help us to determine these vectors and their respective angles.

 

 

NEXT WEEK (10/28 - 11/1):

This week we will apply our understanding of vector analysis to projectile problems. There are 2 types of motion that we will study in regards to projectiles. First we will calculate quantities when an object is launched horizontally from a certain height - where there is only an initial x - component for motion. Then, we will calculate quantities when an object is launched at an angle, giving it both an initial x - component and an initial y - component for motion.
