WebApr 4, 2014 · The amount of energy given to a system by a force is called the work. This is computed by calculating the projection of the force onto the displacement made by the object. (Change in Energy) = W = F → ⋅ d l → = F d l cos ( θ) This means that you don't necessarily need to input energy when exerting a force. Example 1 The parallelogram of forces is a method for solving (or visualizing) the results of applying two forces to an object. When more than two forces are involved, the geometry is no longer parallelogrammatic, but the same principles apply. Forces, being vectors are observed to obey the laws of vector addition, and so the overall (resultant) forc… can my pet bird get covid

WebThe force F that the system exerts on the nucleus is the expectation value of minus the gradient of V (x), where V is the potential that acts on the nucleus. This theorem was originally derived by Ehrenfest (1927), and was used in Hellmann s (1937) treatise to establish the forces in a molecule. Feynman (1939) independently derived the result ... fixingscenter.co.ukWebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889.
