4. Laws of Motion Formulas:

Laws of Motion are fundamental to Physics, and they are widely used in the JEE mains exam. The following are some of the essential formulas related to these laws:

• $F = ma$: This formula relates the force applied to an object, its mass, and acceleration. Here, 'F' is the force applied, 'm' is the mass of the object, and 'a' is its acceleration.

• ${{\rm{F}} = \mu N}$: This formula relates the force of friction, the coefficient of friction, and the normal force. Here, 'F' is the force of friction, '{\mu }' is the coefficient of friction, and 'N' is the normal force.

• $Fg = mg$: This formula relates the force of gravity, the mass of an object, and the acceleration due to gravity.

5. Heat and Thermodynamics Formulas:

Heat and Thermodynamics is an important topic in JEE Physics, and it covers a wide range of concepts such as Heat Transfer, Thermodynamic Processes, and Laws of Thermodynamics.

Understanding the formulas related to these concepts is essential for solving numerical problems in the JEE Physics exam. In this short note, we will discuss some of the essential Heat and Thermodynamics formulas and how to apply them.

a. Heat Transfer Formulas:

Heat Transfer is the study of the transfer of thermal energy between different objects. The following are some of the essential formulas related to heat transfer:

• ${Q = mc\Delta T}$: This formula relates the amount of heat transferred, the specific heat capacity, the mass of the object, and the temperature change. Here, 'Q' is the amount of heat transferred, 'm' is the mass of the object, 'c' is the specific heat capacity, and '${\Delta T}$' is the temperature change.

• $Q = ml$: This formula relates the amount of heat required to change the state of a substance, the mass of the substance, and the latent heat of fusion/vaporisation. Here, 'Q' is the amount of heat required, 'm' is the mass of the substance, and 'l' is the latent heat of fusion/vaporisation.

These formulas are used to solve numerical problems related to heat transfer, such as finding the amount of heat transferred between two objects or the amount of heat required to change the state of a substance.

b. Thermodynamic Processes Formulas:

Thermodynamic Processes refer to the changes in the state of a system due to changes in temperature, pressure, or volume. The following are some of the essential formulas related to thermodynamic processes:

• ${PV = nRT}$: This formula relates the pressure, volume, number of moles, gas constant, and temperature of an ideal gas. Here, 'P' is the pressure, 'V' is the volume, 'n' is the number of moles, 'R' is the gas constant, and 'T' is the temperature.

• ${Q = \Delta U + W}$: This formula relates the heat supplied to a system, the change in its internal energy, and the work done on it. Here, 'Q' is the heat supplied, '{\Delta U}' is the change in internal energy, and 'W' is the work done on the system.

These formulas are used to solve numerical problems related to thermodynamic processes, such as finding the change in internal energy of a system or the work done on it.

c. Laws of Thermodynamics Formulas:

In entropy, 'Q' is the heat transferred, and 'T' is the temperature. The Laws of Thermodynamics are fundamental to understanding heat and thermodynamics. The following are some of the essential formulas related to these laws:

• ${\Delta S = \dfrac{Q}{T}}$: This formula relates the change in entropy, the amount of heat transferred, and the temperature of the system. Here, 'ΔS' is the change. 

• ${\Delta U = Q - W}$: This formula relates the change in internal energy, the heat supplied to the system, and the work done on the system. Here, 'ΔU' is the change in internal energy, 'Q' is the heat supplied, and 'W' is the work done on the system.

To apply these formulas, you need to understand the concept behind them and identify the relevant variables. You should also be familiar with unit conversions and use the appropriate units for each variable. Practice solving numerical problems based on these formulas regularly to improve your problem-solving skills.
