WebTo prove that Kinetic Energy is ½ mv^2 We already know that Energy w = f x s that is force x displacement. So, ΔK = W = FΔs = maΔs From the third equation of motion that is v^2 - u^2 = 2aΔs (-1) where v = final velocity, u = initial velocity, a = acceleration, and Δs denotes change in displacement ΔK = maΔs, so from equation (1) WebIn speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble or deflector shield, is a barrier made of things like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, plasma, particles, radiation, solid light, or pure force.It protects a person, area, or object …
Potential energy - Wikipedia
WebPotential energy is the energy a system has due to position, shape, or configuration. It is stored energy that is completely recoverable. A conservative force is one for which work done by or against it depends only on the starting and ending points of a motion and not on the path taken. We can define a potential energy for any conservative force. WebThe answer is that Hooke's law only applies over a limited range of deformation. It corresponds to a linear approximation to F (r), passing through the point (r 0 ,0), where r 0 is the unstressed length. Integrating Hooke's law gives a potential energy U (r) that is parabolic about the minimu at r 0. philly living
