Displacement is a fundamental concept in the field of Physics, particularly in Mechanics and Kinematics. It refers to the change in position of an object, taking into consideration not just the distance travelled, but also the direction. A keen understanding of displacement and how it relates to average velocity and time is crucial in comprehending motion. This tutorial will explore the formula associated with displacement, its real-life applications, and the prominent individuals who have contributed to this field.

|Displacement (Δx) =|
|Average velocity ( vavg) =|
|Time (t) =|
The displacement (Δx) of an object moving with an average velocity (vavg) over a period of time (t) can be calculated using the following formula:
The concept of displacement and its formula are fundamental to physics and have been known since the time of Galileo Galilei in the early 17th century. This formula is also applicable in other fields such as engineering, where it aids in understanding the motion of mechanical systems, and in navigation, for calculating the position of vessels or aircraft.
Consider a car that travels from Los Angeles to Las Vegas, a distance of 270 miles, in 4.5 hours. The average velocity of the car can be calculated by the displacement (270 miles) divided by the time (4.5 hours), giving 60 miles/hour.
Galileo Galilei (1564-1642) and Sir Isaac Newton (1643-1727) are key figures in the study of motion and displacement. Galilei's experiments laid the groundwork for the laws of motion, while Newton refined and formalized these laws in his three laws of motion, providing the foundation for classical mechanics.
Understanding displacement, average velocity, and time is essential in the field of Physics, specifically in Mechanics and Kinematics. This fundamental understanding has vast implications in various fields, ranging from engineering to navigation, and continues to be an area of active research and development.
