    The maximum value of static friction when the object just begins to move is called limiting friction.

    Maximum value of static friction

    1Thank You

    Yogita Ingle 4 years, 3 months ago

    The amount of friction that can be applied between two surfaces is limited and if the forces acting on the body are made sufficiently great, the motion will occur. Hence, we can define limiting friction as the maximum value of static friction that comes into play when the body is just at the point of sliding over the surface of another body. Limiting friction is the product of normal force and coefficient of limiting friction. Mathematically, this is represented as

    F=muN

    Here,mu is the coefficient of limiting friction and N is the normal force

    The limiting friction is always opposite to the motion of the object.

    When displacement occurs in the direction of applied force it is known as the work done. W=F*s

    Work is defined as the product of force (F) and the actual distance (S) moved by the body in the direction of application force. It is a scalar quantity. In mathematics, work = force ×distance i.e, W = F×S

    0Thank You

    Yogita Ingle 4 years, 3 months ago

    Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of applied force.
    It is measured by the product of the force and the distance moved in the direction of the force, i.e., W = F-S

    As the body continues to move without change in velocity, we consider it as zero impulse. This can be proved numerically. m1 = m2 = 0.05 kg U1 = V1 = 6m/s U2 = V2 = -6 m/s Impulse = Force × time =ma × t = m( v-u)/t × t = m(v - u) Impulse on 2 by 1 = m1 (v1 -u1) = m1(0) =0 Impulse on 1 by 2 = m2(v2-u2) =0

    The branch of physics that defines motion with respect to space and time, ignoring the cause of that motion, is known as kinematics.

    Kinematics equations are a set of equations that can derive an unknown aspect of a body’s motion if the other aspects are provided.

    These equations link five kinematic variables:

    • Displacement (denoted by Δx)
    • Initial velocity (v0)
    • Final velocity (denoted by v)
    • Time interval (denoted by t)
    • Constant acceleration (denoted by a)

    In rotation the body's centre of mass does not undergo any translation motion. In other words the centre of mass will remain at on place. Like a top spinning on its axis.

    In circular motion the body's centre of mass goes around a fixed centre maintaining a constant distance from it. Which means the centre of mass is actually going through a translation motion. For example an ant sitting on the circumference of the spinning top in the above example.

    ANSWER
    The zeroth law of thermodynamics states that ‘two systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other’. The Zeroth Law leads to the concept of temperature. 2. Internal energy of a system is the sum of kinetic energies and potential energies of the molecular constituents of the system. It does not include the over-all kinetic energy of the system. Heat and work are two modes of energy transfer to the system. Heat is the energy transfer arising due to temperature difference between the system and the surroundings. Work is energy transfer brought about by other means, such as moving the piston of a cylinder containing the gas, by raising or lowering some weight connected to it. 3. The first law of thermodynamics is the general law of conservation of energy applied to any system in which energy transfer from or to the surroundings (through heat and work) is taken into account. It states that ∆Q = ∆U + ∆W where ∆Q is the heat supplied to the system, ∆W is the work done by the system and ∆U is the change in internal energy of the system. Now suppose η R < ηI i.e. if R were to act as an engine it would give less work output than that of I i.e. W < W ′ for a given Q1 . With R acting like a refrigerator, this would mean Q2 = Q1 – W > Q1 – W ′. Thus, on the whole, the coupled I-R system extracts heat (Q1 – W) – (Q1 – W ′) = (W ′ – W ) from the cold reservoir and delivers the same amount of work in one cycle, without any change in the source or anywhere else. This is clearly against the Kelvin-Planck statement of the Second Law of Thermodynamics. Hence the assertion ηI > η R is wrong. No engine can have efficiency greater than that of the Carnot engine. A similar argument can be constructed to show that a reversible engine with one particular substance cannot be more efficient than the one using another substance. The maximum efficiency of a Carnot engine given by Eq. (12.32) is independent of the nature of the system performing the Carnot cycle of operations. Thus we are justified in using an ideal gas as a system in the calculation of efficiency η of a Carnot engine. The ideal gas has a simple equation of state, which allows us to readily calculate η, but the final result for η, [Eq. (12.32)], is true for any Carnot engine. This final remark shows that in a Carnot cycle, 2 1 2 1 T T = Q Q (12.33) is a universal relation independent of the nature of the system. Here Q1 and Q2 are respectively, the heat absorbed and released isothermally (from the hot and to the cold reservoirs) in a Carnot engine. Equation (12.33), can, therefore, be used as a relation to define a truly universal thermodynamic temperature scale that is independent of any particular properties of the system used in the Carnot cycle. Of course, for an ideal gas as a working substance, this universal temperature is the same as the ideal gas temperature introduced in section 12.11. I R W Fig. 12.12 An irreversible engine (I) coupled to a reversible refrigerator (R). If W ′ > W, this would amount to extraction of heat W′ – W from the sink and its full conversion to work, in contradiction with the Second Law of Thermodynamics. 2020-21
