## Important Topics for SS Krotov Science for Everyone – Problems in Physics Solutions Chapter 1: Mechanics

Kinematics: Kinematics relates to the study of any object in motion and how they are related. The four kinematic equations in relation to displacement (D), Acceleration (a), time (t) and Velocity (v) are

• D = vit + 1/2 at2
• (vi+vf)/2 = D/t
• a =(vf – vi)/t

Rotational Motion: When a rotational force is applied to anybody, it offers a twist and this leads to rotational motion. It is a translational motion with force being the cause.

Properties of Solids and Liquids: There are three states of matter existing among which solids and liquids are primary states with some definite volume and shape.

Laws of Motion: The three physical laws called Newton’s law of motion lays down the basic foundation of Mechanics. According to the first law of motion, an object tends to remain in rest or motion unless an external force is applied. The second law of motion states the total sum of Force on an object is equal to the mass of the object multiplied by its acceleration F=ma.

Gravitation Work: The force of attraction that acts between all matters is called gravitational force and is calculated by the acceleration that it gives to the object that is falling.

Energy and Power: Energy is called the amount of work that is done by force and power rate at which the work is done. There exist different forms of energy and power.

P =W/t, Where P is power, W is work and t is time.

Oscillation & Waves: This includes various concepts like simple harmonic motion, resonance, oscillation systems.

Thermodynamics: It is based on the relation between heat and other forms of energy. There are four laws of dynamics.

• Zeroth law: When two thermodynamics are in thermal equilibrium with another, then they exist in thermal equilibrium with each other.
• First law: Energy can neither be created nor destroyed but can only change forms.
• Second law: When entropy of any isolated system does not exist in equilibrium will keep a tendency to enhance with time.
• Third law: When the temperature approaches an absolute zero, the entropy of that system approaches a consistent minimum.

Kinetic Theory of Gases: It explains the overall properties of gases like pressure, volume and temperature by taking into consideration the molecular composition and motion. The kinetic theory also called collision theory has three main components

• There is no gain or loss of energy when there is a collision of molecules.
• The molecules present in a gas take a negligible amount of space.
• The molecules are always in a consistent and linear motion.
