WebIntensity (physics) In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m 2 ), or kg ⋅ s −3 in base units. Intensity is used most frequently ... WebInelastic Collision. An inelastic collision is one in which the internal kinetic energy changes (it is not conserved). Figure 8.7 shows an example of an inelastic collision. Two objects that have equal masses head toward one another at equal speeds and then stick together. Their total internal kinetic energy is initially 1 2 mv 2 + 1 2 mv 2 ...
