  • Lower Sec Science: Forces and Transfer of Energy

    This post is about Lower Sec Science: Forces and Transfer of Energy. Summary Pointers Force:Force is a push or pull acting upon an object.It is a vector quantity, meaning it has both magnitude and direction.Newton’s laws of motion describe the behavior of forces.Forces can cause objects to accelerate, decelerate, or change direction.SI units of force…

  • Physics – Understanding different forms of energy stores and energy conversions

    This post is about Physics – Understanding different forms of energy stores and energy conversions. Energy stores and conversions are fundamental to physics. Let’s explore the essential concepts you need to know to tackle these questions with ease! Summary pointers for energy stores: Energy Stores: NOTE: Light energy, sound energy, electrical energy are not energy…

  • Physics – Sound (speed of sound, echo)

    This post is about Physics – Sound (speed of sound, echo). Speed of Sound:Definition: The rate at which sound waves travel through a medium. Dependence on Medium: Temperature Effect:In gases, sound speed increases with temperature. Typical Speeds:Air (20°C): ~343 m/sWater: ~1,480 m/sSteel: ~5,960 m/s Echo:Definition: The reflection of sound waves off a surface back to…

  • All About Converging Len Ray Diagrams

    This post is All About Converging Len Ray Diagrams. Note that the focal length is the distance between an optical lens or mirror and its focal point, where parallel rays of light converge or appear to diverge. Key differences between convex and concave lenses: Shape:Convex Lens: Thicker at the center and thinner at the edges,…

  • Common O-Level Physics Mistakes (Part 2)

    In our last post, we talk about some common O-Level Physics mistakes (Part 1). This week, we’re diving into Part 2. Pressure in Fluids Common Misconception: Students sometimes confuse pressure with force.Pressure (P): Defined as the force per unit area, given by the formula P = F/Awhere F is the force applied and A is the…
