Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an aobject to acquire angular acceleration.Torque is a vector quantity. The direction of the torque vector depends on the direction of the force on the axis.

The Rotational Analog to Mass-- The rotational motion analogy to inertia is rotational inertia (or rotational mass), or in very technical language, moment of inertia. With a given net torque, Στ, different objects will experience different rotational accelerations.

Work can be defined as transfer of energy. If one object transfers (gives) energy to a second object, then the first object does work on the second object. Work is the application of a force over a distance.
Lifting a weight from the ground and putting it on a shelf is a good example of work. The force is equal to the weight of the object, and the distance is equal to the height of the shelf (W= Fxd). Work-Energy
. Energy can be defined as the capacity for doing work. The simplest case of mechanical work is when an object is standing still and we force it to move.
The energy of a moving object is called kinetic energy
. For an object of mass m, moving with velocity of magnitude v, this energy can be calculated from the formula E= 1/2 mv^2.
Types of Energy:
There are two types of energy in many forms:
Kinetic Energy = Energy of Motion Potential Energy = Stored Energy Forms .
Power is the work done in a unit of time. In other words, power is a measure of how quickly work can be done .
The unit of power is the Watt = 1 Joule/ 1 second.
One common unit of energy is the kilowatt-hour (kWh). If we are using one kW of power, a kWh of energy will last one hour.
Calculating Work, Energy and Power WORK = W=Fd
Because energy is the capacity to do work , we measure energy and work in the same units (N*m or joules). POWER (P) is the rate of energy generation (or absorption) over time: P = E/t Power's SI unit of measurement is the Watt,

Water is more elastic than air because bulk modulus of elasticity is reciprocal of compressibility and air is more compressible than water.
