Units and Prefixes Study Guide
Introduction Measurements and observations form the base of our scientific knowledge of the world. Some quantities we measure can be calculated in terms of others, while some cannot; those that cannot are the most fundamental quantities. The International ...

Scalars and Vectors Study Guide
Introduction We start this lesson by briefly considering a reference frame and the coordinates of a point-like object relative to it. Next, we make a distinction between scalar and vector quantities, and present examples of both. At the end of the chapter, we take ...

Motion in One Dimension Study Guide
Introduction We start the article by defining the notions of displacement, velocity, speed, and acceleration, Then we look into graphical representation of motion as a way of describing the motion of an object or particle, We consider a special case of ...

Newton's Laws of Motion Study Guide
Introduction From the previous chapters on physical quantities and their corresponding units, you now know that the unit for mass, kilogram, is a fundamental unit. Mass might also be called a fundamental quantity. It relates to motion, ...

Linear Momentum Study Guide
Introduction In this lesson, we will be studying objects in motion from the point of view of the velocity and mass they carry, This concept we call momentum. One more time we will find a connection between motion and interaction: in this case, a more ...

Mechanical Energy Study Guide
Introduction In this lesson, we will pull all the knowledge about mass, motion, and forces together in a concept that, while very abstract, is at the essence of science and nature – energy, In this lesson, we will concentrate on a form of energy that ...

Uniform Rotational Motion Study Guide
Introduction Motion in one dimension are concepts such as displacement, speed and velocity, and acceleration, We will be following these concepts, but in this case, for a circular trajectory, We will end the lesson by studying the centripetal force, acceleration, ...

Rotational Equilibrium Study Guide
Introduction In this lesson, we will approach a more complex system, a rigid object that has constraints that do not permit a linear motion but allow circular motion. We will define moment of inertia and torque inertia, and we will apply the ...

Properties of Matter Study Guide
Introduction There is a field of physics that studies the mechanical behavior of rigid objects, The objects of study were found in a solid state, they were rigid (of fixed shape and volume), and they were acted on by forces, In this lesson, we will study different ...
