QA › Physics › In an inelastic collision, which of the following quantities is conserved?

In an inelastic collision, which of the following quantities is conserved?

A. Total kinetic energy

B. Total mechanic energy

C. Total linear momentum

D. Speed of each body

Answer: B. Total mechanic energy

An inelastic collision is a form of collision where kinetic energy is lost and linear momentum is conserved. Inelastic collision, however, both kinetic energy and momentum are conserved. In an inelastic collision, the kinetic energy present is transferred to something else in the form of sound energy, thermal energy, and deformation of the material. In summary, the kinetic energy lost in an inelastic collision is in no way lost; rather, this energy is conserved into other forms of energy and this is as a result of internal friction. Inelastic collision does not obey the law of conversation of momentum

Math Calculus — AID—

Total time spent: 4 hours 15 minutes (it is equivalent to 255 minutes). Let the flight time from Paris to Glasgow be X. Then the flight time from Glasgow to Paris will be (X+10). We have an equation with one unknown variable: X + 45 + (X+10) = 255 ⇒ X = 100 So the […]

What were the typical crafts for Maya?

Mayans are well-known as great pottery makers. They did not use the pottery wheel. However,the tecnique they used was coiling consecutive rings of clay on top of each other and smoothing the surface by hand. Also, they were good when it came to working with stone – stone craving is another important craft of Maya. Many […]

What defines a free market?

The efficient working of a free market economy requires that the producer firms must have incentives to work hard and produce goods and services at the lowest possible cost per unit of output Market economies provide incentives to the firms and individuals by recognising and enforcing the property rights of the individuals and firms to […]

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]

Cigarette smoking causes emphysema.

Nearly everyone knows that smoking causes lung cancer, but did you know that smoking causes a number of other serious lung diseases? These include chronic bronchitis and emphysema, collectively known as chronic obstructive pulmonary disease (COPD). COPD is the fourth largest killer of Australians and smoking is the most important risk factor for COPD. When […]
