Rectilinear motion—the movement of a particle along a straight line—is one of the most fundamental topics in differential and integral calculus. For engineering students, particularly those from the University of the Philippines Diliman (UPD) and readers of the renowned Mathalino online community, mastering this topic is non-negotiable. It forms the backbone of dynamics, physics, and even structural engineering.
Here are examples following the Mathalino methodology, illustrating different scenarios. Example 1: Constant Acceleration (Kinematics) Problem: A car starts from rest ( ) and accelerates uniformly at . What is its velocity and distance traveled after Solution: Velocity: Distance: Example 2: Variable Acceleration ( Acceleration ( ) : The time rate of change of velocity
