## 19 Science and Mathematics Formulas for WASSCE

Here are 20 science and mathematics formulas with explanations of when each formula is used:

- Velocity = Distance / Time: This formula is used to calculate the velocity of an object in motion, where distance and time are known.
- Acceleration = (Final Velocity – Initial Velocity) / Time: This formula is used to calculate the acceleration of an object, given its change in velocity and the time over which the change occurs.
- Force = Mass x Acceleration: This formula is used to calculate the force acting on an object, given its mass and acceleration.
- Work = Force x Distance: This formula is used to calculate the amount of work done on an object, given the force acting on it and the distance over which the force is applied.
- Power = Work / Time: This formula is used to calculate the power of a system or device, given the amount of work done over a given time period.
- Kinetic Energy = (1/2) x Mass x Velocity^2: This formula is used to calculate the kinetic energy of an object in motion, given its mass and velocity.
- Potential Energy = Mass x Gravity x Height: This formula is used to calculate the potential energy of an object at a certain height, given its mass and the gravitational acceleration.
- Density = Mass / Volume: This formula is used to calculate the density of an object, given its mass and volume.
- Pressure = Force / Area: This formula is used to calculate the pressure exerted by an object, given the force it exerts and the area over which it exerts the force.
- Boyle’s Law: P1V1 = P2V2: This formula is used to describe the relationship between pressure and volume of a gas, assuming constant temperature.
- Charles’s Law: V1/T1 = V2/T2: This formula is used to describe the relationship between volume and temperature of a gas, assuming constant pressure.
- Ideal Gas Law: PV = nRT: This formula is used to describe the behavior of an ideal gas in terms of its pressure, volume, temperature, and number of molecules.
- Quadratic Formula: x = (-b ± √(b^2 – 4ac)) / 2a: This formula is used to solve quadratic equations of the form ax^2 + bx + c = 0.
- Pythagorean Theorem: a^2 + b^2 = c^2: This formula is used to calculate the length of the hypotenuse of a right triangle, given the lengths of the other two sides.
- Law of Sines: sin(A) / a = sin(B) / b = sin(C) / c: This formula is used to calculate the sides and angles of a triangle, given the lengths of some sides and/or the measures of some angles.
- Law of Cosines: a^2 = b^2 + c^2 – 2bc cos(A): This formula is used to calculate the sides and angles of a triangle, given the lengths of some sides and/or the measures of some angles.
- Exponential Growth Formula: P(t) = P0 e^(rt): This formula is used to describe the growth of a population or quantity over time, assuming exponential growth.
- Logarithm Formula: logb(x) = y: This formula is used to calculate the logarithm of a number x to the base b, resulting in a number y.
- Quadratic Regression Formula: y = ax^2 + bx + c: This formula is used to fit a quadratic curve to a set of data points, where a, b, and c are constants.
