Tags Mechanics Physics Potential In summary, the question posed is to calculate the work done in a steel wire that is 2.0m long and has a cross-sectional area of 0.010cm², with a modulus of elasticity of 200GPa, when it extends by 2.5mm when loaded. The formula for work done is ...
Work energy theorem According to this theorem, $W={K_f} - {K_i}$ = increase in $K.E.$ of the body Here, ${K_f}$ and ${K_i}$ are the final and initial kinetic energy of the body. Potential energy of a spring The potential energy formula of a spring is $P.E.=\dfrac{1...
Some common forms of energy include the kinetic energy, it is of a moving object. The potential energy is stored by an object’s position in a force field. It can be gravitational, electric or magnetic. The elastic energy is stored by stretching solid objects. The chemical energy that is ...

Energy Definition Energy is defined as the capacity to do work. Formula The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh Unit The SI unit of energy is Joules (J). Power Definition Power is defined as...
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...

Application of Work-Energy Theorem The application of the Work-Energy theorem is that it is very useful in analyzing situations where a rigid body should move under several forces. A rigid body cannot store the potential energy in its lattice due to its rigid structure and it can only possess...
A) Kinetic B) Potential C) Electrostatic D) Nuclear Solution: A) The Gravitational Potential energy, Nuclear and Kinetic Energy all depend on mass. But out of the three only Kinetic energy is such that it contains the term with the square of velocity. So the answer is A. Q 2: A rigid...
