What are the Important Science Formulas for Class 10 Science?

Most students are afraid of physics because of complex numerical problems. However, the subject can become much more enjoyable once students are familiar with physics formulas. Memorizing all the physics formulas can be difficult. Keep that in mind; we have compiled a comprehensive list of the class 10 physics formulas most commonly used and encountered in physics. These physics formulas will help 10th Class students for Class 10 Board Exam preparation and help them in the latter stages of preparing for competitive exams like JEE & NEET.

To study a complete list of science formulas, check-out NCERT solutions for class 10 science.

In these NCERT solutions, you will find all essential topics and formulas in easy-to-understand language.

Most Important Science Formulas for Class 10

1. Kinetic Energy

Kinetic Energy is a type of energy that helps an object to maintain its motion state. When a net force is applied to an object it gains some speed and eventually gains kinetic energy. Kinetic Energy is also called energy of motion so any object that is in motion have kinetic energy.

The formula of kinetic energy is

2. Torque

Torque is also called the moment of force. Torque is a force that has the tendency to rotate it on its axis. Torque is also called a twisting force that causes motion. It is also referred to as the turning effect. The point of rotation of an object is also called the axis of rotation. The SI Unit for torque is Nm(newton-meter).

The Formula for Torque is:

3. Vector Formula

A vector is a quantity in physics that has both magnitude and direction. It is usually represented by an arrow whose direction corresponds to the direction of quantity and whose length is proportional to the extent of the quantity. Vectors have magnitude and direction but no position.

4. Gravity Formula

In physics, gravity is the force of attraction between two masses. Believe it or not, every particle in the universe has a gravitational effect on every other particle. The terms “gravity” and “gravitation” are frequently used vice-versa to refer to the attraction of anything that has energy or mass.

5. Work, Power, and Energy Formula

Work, Energy, and Power are Core concepts of Physics. The amount of work is required to move an object is called work. We define the ability to do the work as energy. Power is defined as work done in the per unit of time.

6. Waves Formula

Wave motion is the transfer of energy and momentum from one point of the medium to another medium without the actual transport of matter between two points.

Wave motion, propagation of disturbances — that is, deviations from a state of rest or equilibrium — from place to place in a regular and organized way. We all are familiar with the surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles manifests wavelike properties.

7. Reflection of Light

The reflection of light in a mirror is the best example of light reflection. The light waves are reflected so strongly on the shiny, flat surface of the mirror glass that they obey two laws of light reflection. Regular reflections occur on plane mirrors. Light reflection is a phenomenon where light is reflected off the same medium as it hits the surface of an object. The two laws of reflection are: (i) The incident ray, the reflected ray, and the normal (at the point of incidence) are in the same plane.

8. Thermodynamics

We study the relationship between heat, work, temperature, and energy in thermodynamics. The laws of thermodynamics describe how energy changes in a system and whether a system can do valuable work for the surroundings. The SI unit of thermodynamics is Kelvin(k). Sometimes we also use degree celcious(℃).

Heat and Temperature:

In thermodynamics, heat and temperature are concepts closely associated with precise definitions. Heat, start text, q, and end text are the heat energy transferred from the hottest contact to the coldest system. Temperature measures the standard kinetic energy of atoms or molecules in a system.

Heat Formula:

Temperature Scale:

℉ = 32 + 9/5C, K = C + 273.16

• Specific Heat

C =Q/QmΔT

• Ideal Gas Equation:

PV = nRT

Here n: number of moles
