Physics
Physics is one of my favourite subjects. The course is appropriately challenging, as it requires us to synthesise solutions by applying the formulas learned in class. Solving physics problems feels like working through a puzzle, as one must identify the key elements of a question and determine the correct approach to arrive at a solution. Studying classical physics is fascinating, as it provides a foundational understanding of how the world works.
Acceleration on an Inclined Plane
This assignment is a physics lab investigation that examines how the acceleration of an object on an inclined plane depends on the angle of the ramp. We first measure a cart’s velocity at different positions using a photogate, linearize the data by graphing v² vs. displacement, and use the slope to calculate the cart’s experimental acceleration. We can then compare these results to the theoretical acceleration, calculate percent error, and analyze sources of discrepancy such as friction and measurement limitations.

This assignment applies kinematics and real-world constraints to determine a safe yellow-light duration at a traffic intersection. You model a car traveling at the speed limit with constant acceleration/deceleration, define stop and go zones, and derive an equation for the minimum yellow-light time that allows a driver to either stop safely or clear the intersection completely. The task requires justifying assumptions, refining an initial approach, deriving a final formula, and discussing how variables like speed limit, reaction time, braking ability, and vehicle length affect traffic safety.
