Physics is an abundance of formulae, and it is impossible to compile them all in one single book. Every law of physics has various formulae to calculate the different aspects. However, everything in physics is based on calculations and you can study the relativity using the quantitative measurements. |
Nonetheless, the best possible thing to do is to construct your own formula sheet based on the subject that you are learning in physics. For example, if you are learning about the laws of motion in physics, you should make notes on all the formulas related to the laws of motion. There will be several things to calculate such as force, direction, velocity, speed and momentum. Make a list of formulas pertaining to these topics.
Some of the most important definitions and laws of physics are Newton’s laws of motions. These cover a huge number of formulas and are crucial for calculating several things even in advanced physics.
Here are a few examples:
Second Law of Motion states that the acceleration of a body is directly proportional to the net unbalanced force and inversely proportional to the body's mass, a relationship is established between force (F), mass (m) and acceleration (a). So, the formula for calculating force is as follows:
F = m X a
Momentum (p) is the quantity of motion in a body. A heavy body moving at a fast velocity is difficult to stop. A light body at a slow speed, on the other hand can be stopped easily. So, momentum has to do with both mass (m) and velocity (v), and you can calculate using the following formula:
p = mv
Impulse can be defined as the change in momentum of a body that occurs over an extremely short period of time. So, if m is the mass of the body, and v and u are the final and initial velocities, then impulse can be calculated using the following formula:
Impulse = Ft = mv - mu
