Physics Formulas for Class 12

Physics formulas, concepts, and challenges assist us in applying physics in our everyday lives to better comprehend how the world works. The advancement of physics concepts aids in the development of new technologies in our environment. Developments in thermodynamics, for example, led to the rise of industrialization, while advances in nuclear physics and electromagnetism led to the invention of new items such as television, computers, nuclear weapons, and a variety of home appliances. When one learns the theories and concepts of physics, they may deduce the relationship between various quantities, which can then be utilised to deduce the Physics formulae that are used to solve problems and develop the fundamentals.

Speed formula

The rate at which an object travels a certain distance is determined by the speed formula. The distance travelled by a body in a given length of time is known as its speed. ms is the unit of speed.

Formula for speed is given as:

s=d/t

Where s is the seed

d is the distance travelled and

t is the total time taken

Velocity formula

It relates to the rate at which displacement changes over time. Moreover, the velocity is defined by distance and displacement. If the item’s potion is empty and the thing does not travel any distance, there will be no velocity. It’s unit is m/s.

As we know

displacement=final position-initial position

t = total time taken

Hence,  velocity=displacement / time=(final position-initial position)/time

Acceleration formula

Acceleration can be defined as a process of increasing speed. However, we can see that it means something different from a physics point of view. It’s referred to as the rate at which an object’s velocity changes over here. It doesn’t matter if it’s speeding up or slowing down; what matters is the change. The formula of acceleration will be given as:

a=v_f -v_i /t

Here a is the acceleration

And  v_f -v_i /t is the rate of change in velocity with respect to time

Essential use of Physics formulas

Students who have a solid understanding of physics are more likely to achieve higher grades in competitive exams. Physics formulas are developed and thoroughly explained. Our team’s most important goal is to provide a solid conceptual foundation.

using physics formula

Exams and their difficulty levels are taken into account when formulating Physics formulae. Physics is made up of a variety of standard numerical formulas based on length. Most people skip through the most numerical sections because they can’t remember the formulas. Students are given derivations based on formulas in Physics formulas. The formulas for Physics are created following a thorough examination of past question papers.

The Physics formulas have been divided into numerous parts to make studying easier. Students will be able to access formulas that are organised by chapters. Exam preparation becomes really simple. Along with these, one student possesses the entire collection of Physics formulas. Because all numerical calculations are based on formulas. Formulas not only help students solve difficult math problems, but they also help them get better grades in their exams.

Use Physics Formula Effectively

The correct method to use physics formula is to read the chapter first and then update the chapter’s entrance physics formula sheet and try to keep in mind all of the formula. After that, start solving numerical problems and try to develop your understanding of the subject and the application of physics formulas. Second, a physics formula pdf sheet is highly advised for last-minute revision during the week leading up to the exam. Read all of the physics formula sheets before your final exam. This will help you finish the syllabus quickly and make the entire revision process go faster. Last-minute revision can help you significantly enhance your grades, so prepare your own notes with the use of a physics formula sheet whenever possible.

Some important physics formula for class 12

Mirror formula

It denotes the mathematical relation between the object distance (u), image distance (v), and focal length (f). The mirror formula’s expression is:

1/f=1/v+1/u

Heat formula

Specific heat formula

Q =mCΔT  joules /kg K

Here C = proportionality constant

Latent Heat Formula

L=Q/m

Here Q = Heat change

m = mass

L = specific latent heat

Angular speed

An object’s angular speed is the pace at which it rotates. In other words, it’s the change in an object’s angle per unit of time. When computing angular speed, we measure the angle in radians. When measuring angles in radians, the right angle is defined as 2 radians.

Formula will be given as:

angular speed=the total distance covered/time ⍵=θ/t

here θ is expressed in radian.

Time is expressed in seconds.

So, the unit of angular speed is radian/sec

Angular Acceleration

The variation of angular velocity over time is known as angular acceleration, which is obtained from angular velocity. Rotational acceleration is another name for angular acceleration.

The formula of angular acceleration is:

α= dω/dt

Here is the angular acceleration

is the angular velocity

And t is the total time taken
