Boosting your problem-solving skills is a journey, and a handy tip to enhance your memory and proficiency in formulas is to jot them down and place them in your daily view. By physically writing out the key formulas and sticking them on your wall or near your mirror, you create a visual reinforcement that aids in better retention. With time, these formulas become ingrained in your memory, making problem-solving more intuitive. So, whether you’re a student preparing for exams or a professional seeking to excel in your field, this simple yet effective technique can make a significant difference in your formula mastery:
This law explains how all objects in the universe are attracted to each other, with the force being proportional to the product of their masses and inversely proportional to the square of the distance between them (F = G(m1m2/r2)).
Describing the electrostatic force between charged particles, this law states that the force is directly proportional to the product of their charges and inversely proportional to the square of the distance between them (F = k(q1q2/r2)).
Ohm’s Law defines the relationship between voltage, current, and resistance in electrical circuits (V = IR), indicating that current is directly proportional to voltage and inversely proportional to resistance.
Einstein’s famous equation, E = mc^2, reveals the profound connection between mass and energy, suggesting that mass can be converted into energy and vice versa.
This law pertains to the behaviour of gases at a constant temperature and states that the product of pressure and volume remains constant (PV = k).
Describing the behaviour of ideal gases under various conditions, this equation relates pressure, volume, temperature, and the number of moles of a gas (PV = nRT), with R being the gas constant.
This law explains the energy radiated by a black body in relation to its temperature (E = σT^4), where σ is the Stefan-Boltzmann constant.
Snell’s Law is essential in understanding the refraction of light as it passes through different media. It states that the ratio of sines of incident and refracted angles is constant (n1sinθ1 = n2sinθ2), where ‘n’ represents the refractive index.
Physics is a multifaceted discipline that enriches our understanding of the natural world, from the smallest particles to the grandest cosmic scales. These key topics in physics serve as building blocks for countless scientific discoveries and technological innovations, shaping the way we perceive and interact with the universe.

Physics is an amazing subject that goes far beyond just memorising formulas. It’s about understanding how things work in the world around us. While it’s important to know some basic formulas, the real magic happens when we use these formulas to solve problems and discover new things.
Here are some key points to remember:
Physics is divided into different areas like mechanics, thermodynamics, electromagnetism, quantum mechanics, relativity, astrophysics, and atomic/nuclear physics. Each of these areas helps us understand different aspects of the world, from tiny particles to the vast universe.
So, while memorising some formulas can be helpful, it’s even more important to understand the concepts behind them and use them to explore the incredible world of physics. It’s a fascinating journey of discovery that can change the way we see and interact with our universe.
Understanding physics formulas is crucial because it allows you to apply them effectively to real-world problems. Memorization alone won't help you grasp the underlying principles and concepts. When you understand how and why these formulas work, you can adapt them to various situations and develop problem-solving skills that extend beyond exams.
One effective technique is to write down the key formulas and place them in visible locations, such as on your wall or near a mirror. Regularly seeing and reviewing these formulas reinforces your memory. Additionally, practising problem-solving using these formulas helps solidify your understanding.
