# Using Lists & Spreadsheets on a TI-Nspire cx cas Scientific Graphing Calculator

Below are some step-by-step instructions (with pictures) for programming/saving lists of data and using the spreadsheet capabilities on a TI-NSpire CX CAS calculator. 1. With the calculator on, go to the home screen/main menu by clicking the ON button. 2.

# Finding Forces Acting Upon Objects on an Inclined Plane or Ramp with Free Body Diagrams

In both high school physics and general college physics, Free Body (Force) Diagrams are critical in understanding how forces act upon objects that are on an incline. On a flat horizontal surface, such diagrams are pretty straightforward showing that: Gravity

# Vector Addition/Subtraction Calculator and Vector Component Resolver

In the realm of Physics and Math, one of the most useful fundamental concepts studied is how to work with vectors.  Vectors are measurements associated with direction and are used in the fields of construction, air traffic control, nautical navigation,

# Projectile Motion & Parabolic Motion Calculator: Solving 2D Kinematics Problems for Physics

Kinematics, the study of motion, is one of the more grueling units in any physics course.  Often, the curriculum starts out fairly straight forward distinguishing between: Definition Examples Scalar quantities Measurements/values that are never negative Driving 5 miles Distance Speed

# Molar Mass and Mass Percentage Calculator for Chemistry

Calculating Molar Masses and Mass Percentage are fundamental concepts in chemistry.  Molar masses are used throughout stoichiometry problems for liquids, solids, and gases. What exactly is molar mass, and how is it used? The molar mass of a compound (sometimes
