equation for kinetic energy in terms of momentum. The two quantities depend on mass and velocity of body and are related by the equation as above. P 2mK12 That means the square root of 2mK gives us the momentum value.
Therefore we dont need the second term and an objects kinetic energy is just K ½mv2 Derivation using calculus but now we dont need to assume anything about the acceleration. But in a practical situation this may not be the case and the velocity can very across the cross section. P 2mK12 That means the square root of 2mK gives us the momentum value.
Hence the equation is KE p2 2m.
V is the velocity of the object measured in ms. 11-1-99 Sections 87 - 89 Rotational work and energy. Rotational kinetic energy and angular momentum. Which is establish as.
