Ek = 1/2 mv 2. Ek = Kinetic energy. m = mass of the body. v = velocity of the body. Kinetic Energy Formula Derivation. Let us consider the example of an object of m which is at a state of rest on a table. A force F acts on the object which moves it through a distance S. The work done=F x S. W=F net x S——- (1)

Kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Derivation:
In inelastic one dimensional collision, the colliding masses stick together and move in the same direction at same speeds. The momentum is conserved and Kinetic energy is changed to different forms of energies. For inelastic collisions the equation for conservation of momentum is : m1u1 + m2u2 = (m1 + m2) v.
This is the Work-Energy theorem or the relation between Kinetic energy and Work done. In other words, the work done on an object is the change in its kinetic energy. W = Δ (K.E.) The engine of your motorcycle works under this principle. The explosion of the burning mixture of fuel and air moves the piston.
Gravitational Potential Energy Formula. The gravitational potential energy formula is equal to the mass times the force of gravity where g is a constant valued 9.8 \(m/s^{2}\) times the height of the object. Potential energy = mass × gravity × height \(E_{grav}\) = PE = mgh. Derivation of the Gravitational Potential Energy Formula. m = refers ...
The above diagram represents the motion of an object under the influence of gravity. It is an example of projectile motion (a special case of motion in a plane). The motion of a projectile is considered as a result: Few Examples of Two – Dimensional Projectiles. Throwing a ball or a cannonball. The motion of a billiard ball on the billiard table.
The total mechanical energy of the wave is the sum of its kinetic energy and potential energy. The kinetic energy comes out as, K = 1/ 4(μ A 2 ω 2 λ), where A is the amplitude of the wave (in metres), ω is the angular frequency of the wave oscillator(in hertz), λ is the wavelength (in metres). The potential energy also comes out as,
W 1 = P 1 A 1 (v 1 ∆t) = P 1 ∆V. Moreover, if we consider the equation of continuity, the same volume of fluid will pass through BC and DE. Therefore, work done by the fluid on the right-hand side of the pipe or DE region is. W 2 = P 2 A 2 (v 2 ∆t) = P 2 ∆V. Thus, we can consider the work done on the fluid as – P 2 ∆V.
