Non-Linear Motion

Table of Contents Projectile Motion Analyzing Projectile Motion Examples Circular Motion Projectile Motion Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory. Note that...

Free-Fall Motion

Table of Contents Introduction Examples Introduction Free-fall motion refers to the motion of an object under the influence of the Earth’s gravitational field without air resistance and other frictional forces. Such an object will experience an acceleration due to the gravitational force of the Earth, manifested as its...

Scalars and Vectors

Table of Contents Scalars Vectors Magnitude of a Vector Multiplication of a Vector by a Scalar Addition of Vectors Subtraction of Vectors Components of a Vector Reconstructing a Vector from its Components Calculating Vector Sum using Components Scalars Some quantities in physics, such as time, distance, mass, speed and...

Errors and Uncertainties

Table of Contents Introduction Quantifying Uncertainty Significant Figures Computations with Significant Figures Experimental Errors Random Errors Systematic Errors Accuracy and Precision Propagation of Uncertainties Addition and Subtraction Multiplication and Division Powers and Roots Introduction Taking measurements...

Kinematic Equations

Table of Contents Introduction Uniform Motion Equations of Motion Graphical Methods Uniformly Accelerated Motion Equations of Motion Graphical Methods Introduction In the previous section, we defined the kinematic quantities used in the study of kinematics, including displacement, velocity and acceleration and the...

Kinematic Quantities

Table of Contents Introduction Position and Displacement Time Distance and Average Speed Average Velocity Instantaneous Velocity and Speed Average Acceleration Negative Acceleration vs Deceleration Instantaneous Acceleration Introduction We begin our study of kinematics by defining the kinematic quantities considering...

Physical Quantities

Table of Contents Introduction S.I. Units Base Units Derived Units Prefixes Homogeneity of Equations Introduction In physics, quantities that can be measured are known as physical quantities. Two examples (length and mass) are shown in the following figures. Figure 1a - Measuring length using a ruler. Figure 1b -...

Newton's First Law of Motion

Table of Contents Introduction The Concept of a Force Newton’s First Law of Motion The Concept of Mass The Concept of Weight The concept of Normal Reaction Forces Tension Introduction We begin our study of dynamics by defining the concepts of force and mass. Newton’s First Law of Motion (also called the Law of Inertia)...
