Almost every single number in physics has a unit. This section of resources will introduce units, unit conversions, and doing math with units. To view the units and dimensional analysis resources, click here.
What are position, velocity, and acceleration? How are these concepts related to each other?
There are two main types of numbers in physics: scalar and vector. Scalar numbers are only magnitudes while vectors indicate both a magnitude and a direction.
Some of the main types of problems you will encounter in your beginning physics classes are dynamics and kinematics problems. This section will discuss the similarities and differences between these problems and give example problems and solutions.
One of the most important steps in solving dynamics problems in physics is understanding the concepts of forces and inertia. Forces are any influence that will change the motion of an object. Inertia is an object’s tendency to resist a change in its motion (speed, direction, etc.)
Free body diagrams are a visual aid in which we draw all of the forces acting on an object as vectors.
