What formulas are given in GCSE physics?
In GCSE physics, students are provided with a range of formulas that are essential in understanding and solving various physics problems. These formulas cover different topics such as motion, forces, energy, electricity, and waves.
One important formula in GCSE physics is Newton's second law: force = mass × acceleration. This formula relates the force applied to an object to its mass and the resulting acceleration. It is crucial in understanding the relationship between force, mass, and acceleration.
Another formula students come across is Ohm's law: V = I × R. This formula relates the voltage across a conductor (V), the current flowing through it (I), and the resistance (R) of the conductor. Ohm's law is fundamental in understanding the behavior of electrical circuits and calculating the values of various circuit components.
The formula for calculating kinetic energy is also introduced in GCSE physics: kinetic energy = 0.5 × mass × velocity^2. This formula calculates the energy possessed by an object due to its motion. Knowledge of this formula allows students to understand how speed and mass affect the amount of kinetic energy an object possesses.
Furthermore, the formula for calculating density is given: density = mass/volume. This formula allows students to determine the density of an object or substance by dividing its mass by its volume. Understanding density is important in various applications, such as determining the buoyancy of objects and understanding the behavior of fluids.
The formula for calculating the frequency of a wave is also covered in GCSE physics: frequency = 1/period. This formula helps students understand the relationship between the frequency and the time period of a wave. It is crucial in understanding the properties and behavior of waves, including light and sound waves.
These are just a few examples of the formulas that are given in GCSE physics. Mastering and applying these formulas allow students to solve problems and gain a deeper understanding of the principles and concepts in physics.

One key equation that is frequently provided is Newton's second law of motion: F = ma. This equation relates the force applied to an object, its mass, and the acceleration it experiences. It is often used to calculate the force acting on an object in different scenarios.
Another important equation that is commonly given is Ohm's law: V = IR. This equation represents the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. Understanding this equation allows you to calculate different values in circuits, such as the voltage across a component.
One more equation that you can expect to see on the exam is the wave equation: v = fλ. This equation relates the velocity (v) of a wave to its frequency (f) and wavelength (λ). It enables you to calculate various properties of waves, such as their speed or frequency given the wavelength.
In addition to these fundamental equations, other equations related to topics such as energy, power, magnetism, and optics may also be provided. These equations help you analyze and solve problems in each specific area of physics covered in the GCSE curriculum.
It is important to familiarize yourself with these equations and understand how to apply them in different scenarios. However, it is also crucial to remember that the exam may require you to derive or manipulate equations rather than simply using them in their given form.
