With senior exams approaching and needing to achieve an 80 percent average in order to get into university and land his dream job, Oliver decides to get away from the chaos that is his home life. Fleeing to Sunny Haven Recreation and Leisure Center in a small coastal town, Oliver regrettably discovers that his new study space is home to an array of elderly citizens, all of whom have their own opinions on Oliver's life plans. With time and the help of the residents, Oliver's universe gradually expands as he learns to trust life's lessons and listen to his heart.

• Table of Contents
• Stress = Force/Area
• Weight = Mass x Gravity
• Impulse = Force x Time
• Newton’s First Law of Motion: In the absence of a net force, a body is at rest or moves in a straight line with constant speed.
• Refraction: The change in direction of a wave due to a change of speed.
• Earth’s gravity = 9.81m/sec2
• Newton’s Second Law of Motion: Force equals Mass x Acceleration (F = ma).
• Pascal’s Principle: Pressure exerted anywhere in a confined fluid is transmitted equally in all directions throughout the fluid.
• Any object, wholly or partially immersed in fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. (Archimedes of Syracuse)
• Newton’s Law of Universal Gravitation: Every particle in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
• The de Brogli Hypothesis: All matter, including light, has a wave-like nature.
• Wavelength is determined by velocity divided by frequency (λ = v/ƒ).
• Kepler’s First Law: The orbit of every planet is an ellipse with the sun at a focus.
• Hooke’s Law: The extension of an elastic spring is linearly proportional to its tension (F = kx).
• Ohm’s Law: The current between two points is proportional to voltage and inversely proportional to the resistance between them (R = V/I).
• Newton’s Third Law of Motion: For every action, there is an equal, opposite reaction.
• Einstein’s Theory of Relativity: E = mc2
• Momentum = Mass x Velocity
• Energy cannot be created or destroyed, only changed from one type to another.
