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 ...
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 ...
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 the ra...
Chemical Energy --Chemical energy is a form of potential energy related to the breaking and forming of chemical bonds. It is stored in food, fuels and batteries, and is released as other forms of energy during chemical reactions. Mechanical Energy -- Energy of the moving parts of a machine....
When we lift a load through a height against the force of gravity by applying a force greater than the gravitational force, the work done on the body is eventually stored as the gravitational potential energy of the body. This brings us to the work-energy theorem. Work energy theorem states...
If we want to use the formula of work, we need the friction coefficient to calculate the frictional force. But that is not given. So let's attempt to implement the work-energy theorem. Forces acting on the block are gravity, normal reaction, and frictional force. So, ...

The work function can be calculated by using the following formula: Where, Φ is the work function of the material E k is the kinetic energy of the emitted electron h is the Planck constant f is the frequency of the incident light
The heart rate corresponding to 6.5 METs is calculated by interpolation between the rates at 5.8 and 7.2 METs using the formula: (6.5−5.8)/(7.2−5.8)=0.500.50(150−120)=15+120=135 Average = 67% of functional capacity (0.67 × 7.2 METs = 4.8 METs). Calculation of corresponding...
Kinetic energy can be defined as the capacity of an object to do work by virtue of its motion. Learn formula, equation & examples of Kinetic Energy in detail.
