The energy and momentum formula for 2D water waves in a uniform flow were obtained in the present paper. When uniform flow does not exist, the problem has already been discussed enough. However, when uniform flow does exist, the discussions are not enough. In case of 2D infinite water ...

This formula is based on Einstein's famous equation for the relationship between mass and energy. What is the law of conservation of energy? The law of conservation of energy states that energy cannot be created or destroyed, but can only be transformed from one form to another. This means ...
This post contains all the important formulas that you need for GCE O Level Physics. (Equivalent to American High School Diploma) If you do not recognise any of the formulas listed here, you should go review the respective topic. For definitions, please visitAll Definitions Needed For O Level...
Mechanical kinetic energy of an object of mass m moving with velocity v is given by the formula: KEmech=12mv2 The SI unit for KE is the Joule (J) where 1 J = 1 Nm. The heavier the mass and the faster it is moving, the more kinetic energy it has, but it...
One of the most curious forms of energy comes from the concept of the equivalence of mass and energy, as proposed by Albert Einstein. Einstein showed that for objects travelling with speeds close to the speed of light {eq}c {/eq}, the mass of the object {eq}m {/eq} gives rise to ...
Consider, then, somebody lifting a 1.5-kg physics textbook from the surface of a desk, raising it 50 cm (i.e., 0.5 m) above the surface. What is the gravitational potential energy change (denoted ∆GPE) for the book as it is lifted?
By definition, it is the energy possessed by an object due to its motion. For example, a moving car, a moving cycle and a football in motion are some examples of kinetic energy. Now the question arises what happens to the kinetic energy when an object stops? Well, kinetic energy purely...
to twice the induced current’s magnitude. Thus, we can conclude that if Lenz’s law did not state that the induced current should form a magnetic field to restrict the created field, then we would finish up with a nonstop positive feedback loop for breaking the protection of energy. ...
Overview of Work, Energy and Work Frequently Asked Questions – FAQs What is Work? For work to be done, a force must be exerted and there must be motion or displacement in the direction of the force. The work done by a force acting on an object is equal to the magnitude of the force...
