In physics, we learn a variety of concepts including kinematics, dynamics, energy, momentum, and circular motion. Our curriculum follows the AP Physics Mechanics with Calculus framework, preparing us for the AP exam at the end of the year. Throughout the course, we engage in hands-on experiments and problem-solving activities to deepen our understanding of physical principles and their real-world applications. Some examples include launching nerf guns to understand projectile motion and air resistance as well as using Vernier Graphical Analysis software to analyze motion data collected from cart collisions.
When a car comes to an intersection, and the light turns yellow, it must either stop or go. If the car chooses to stop, it must be able to stop before the white line of the intersection. If it chooses to go, it must completely cross the intersection before the light turns red without accelerating. How long should the light stay yellow? Our model uses the main four kinematics equations to determine how long a yellow light should stay on. We must consider the speed and length of the car and the width of the intersection. We also assume that cars are not speeding up or slowing down and remain at constant speed as they pass through. Our model focuses on the cars that must pass through the intersection during the yellow light. View a more detailed explanation of the model below or here.
In our dynamics lab, we explored the relationship between force, mass, and acceleration. We set up an experiment using a cart on a track connected to two hanging masses via a pulley system. By varying the mass on each side while keeping the total mass of the system constant, we measured the resulting acceleration of the system using motion sensors. Our data collection allowed us to analyze how changes in force (due to the hanging mass) affected acceleration, confirming Newton's Second Law of Motion (F=ma).
