Intro Physics - Kinematics

Setting up kinematic equations for free-fall with and without initial velocity. Solving for the velocity upon impact.

Derivation of kinematic equations for 1D motion with constant acceleration.

Illustration of the relationship between velocity and acceleration. Emphasis on the fact that acceleration is the amount by which velocity changes every second.

Review of the average acceleration vector and deriving the instantaneous acceleration vector from it.

Review of average velocity and definition of the instantaneous velocity.

Definition of the average acceleration vector and illustration of how it represents the amount by which velocity changes every second.

Definition of the average velocity vector and illustration on a couple of examples. Emphasis on why the average speed is not the magnitude of the average velocity.

Introduction to the chapter of kinematics where we define how time and position is measured in Physics.

Brief overview of the particle model which is the fundamental assumption made throughout the first chapters of mechanics.

Definition of the position vector of a point mass moving along a single direction (x-direction).
