Question

the mass of a moving object increases, but its speed stays the same. what happens to the kinetic energy of the object as a result?

Answer 1

Answer:

The kinetic energy of the object increases

Explanation:

The kinetic energy of an object is given by:

$K=\frac{1}{2}mv^2$

where

m is the mass of the object

v is its speed

We see that the kinetic energy is proportional to the mass and to the square of the speed. In this problem, the speed stays the same, while the mass increases: since K is directly proportional to the mass, this means that the kinetic energy of the object increases as well.

Answer 2

That scenario is completely impossible. If it happened, the object"s kinetic energy would increase. The whole thing would require mass materializing out of nothing, and energy being created.
