Products of Vectors Products of Vectors Introduction Vector products allow us to combine vectors in different ways, depending on whether we need a scalar result (dot product) or a vector result (cross product). These operations are essential in physics and engineering for understanding quantities like work, torque, and angular momentum. […]

Unit Vectors Unit Vectors What Are Unit Vectors? A unit vector is a vector with a magnitude of exactly . Unit vectors are used to indicate direction without considering magnitude. They are often employed in physics and engineering to simplify calculations and represent directions. Unit vectors are typically denoted with […]

Components of Vectors Components of Vectors What Are Vector Components? Vector components are the projections of a vector along the coordinate axes. Breaking a vector into its components simplifies calculations in physics, as it allows us to treat each direction independently. For example, a vector in two dimensions can be […]

Vectors and Vector Addition Vectors and Vector Addition What Are Vectors? A vector is a quantity that has both magnitude and direction. Vectors are used to represent physical quantities like displacement, velocity, force, and acceleration. For example, a car traveling north can be represented by a vector with: Magnitude: . […]

Estimates and Orders of Magnitude Estimates and Orders of Magnitude What Are Estimates and Orders of Magnitude? In physics, estimates and orders of magnitude help simplify problems and provide quick approximations. These tools allow us to evaluate the size of a quantity and compare it to others without requiring precise […]

Uncertainty and Significant Figures Uncertainty and Significant Figures What is Uncertainty? Uncertainty represents the range within which a measured or calculated value is expected to lie. All measurements have some degree of uncertainty due to: Limitations of measuring instruments. Environmental factors. Human errors. For example, if the length of a […]

Using and Converting Units Using and Converting Units Why Are Units Important? Units are essential for interpreting measurements and solving problems in physics. They provide a standard for comparing quantities and ensure calculations are consistent and meaningful. For example, the speed of a car can be expressed in , , […]

Standards and Units Standards and Units What Are Standards and Units? Standards and units are the foundation of measurement in science and engineering. A standard is a reference that defines a unit, while a unit is a defined quantity used to express a physical measurement. For example, the meter is […]
