WebSince 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 … WebDevices waste energy for various reasons including friction between their moving parts, electrical resistance, and unwanted sound energy. In most cases, this waste energy is …
WebAug 18, 2024 · At the moment that the object loses all its kinetic energy, the friction force will stop instantaneously, not having any force on the object to make it move in the opposite direction. One analogy that I like is: Consider the object in motion like a car. Imagine that the friction is like the car's brakes, old brakes, that only function partially. WebSince 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. Square root this and you end up with 13.7m/s.
WebMay 26, 2024 · The squeezing and un-squeezing of the materials is not purely elastic and therefore internal friction dissipates energy in the form of heat. This loss of available energy for rolling due to heating is called …

When fluids flow through pipes, energy losses inevitably occur. On the one hand, this is due to friction that occurs between the pipe wall and the fluid (wall friction).On the other hand, frictional effects also occur within the fluid due to the viscosity of the fluid (internal friction).The faster the fluid flows, the greater the internal friction … most in wantWebAnswer: Friction is caused by interlocking of irregularities in the two surfaces, thus it is quite obvious that the Force of friction increases when two surfaces are pressed harder, this … mini cooper paddy hopkirkWebAug 19, 2024 · Combined with the increase in the friction coefficient at a concentration of 0.5 mol/L in reported Section 3.1 (285.24 ± 62%), it can be concluded that a higher concentration of LaCl 3 does not result in a greater degree of sudden increase in friction coefficient.
