Top 4 formulas:
1. Newton's Second Law of Motion:
F = ma
This formula relates the force F acting on an object to its mass m and acceleration a. It is a fundamental law in classical mechanics and describes how the motion of an object changes when a force is applied to it.
2. Newton's Law of Universal Gravitation:
F = (G Β· m_1 Β· m_2)/(r^2)
This formula describes the attractive force between two objects with masses m_1 and m_2 separated by a distance r. G is the gravitational constant.
3. Einstein's Mass-Energy Equivalence (E=mc^2):
E = mc^2
This famous equation from Einstein's theory of relativity states that energy (E) is equal to mass (m) times the speed of light (c) squared. It highlights the relationship between mass and energy.
Ohm's Law relates the voltage (V) across a conductor, the current (I) flowing through it, and the resistance (R) of the conductor. It is essential in understanding the behavior of electrical circuits.
4. Coulomb's Law:
F = (k Β· |q_1 Β· q_2|)/(r^2)
