Answer:
Kinetic energy and mass are directly proportional to each other
Step-by-step explanation:
As we know by the formula of kinetic energy
![KE = (1)/(2)mv^2](https://img.qammunity.org/2020/formulas/physics/middle-school/75r8c43zrsqvlsinc4j82yse5odixy3cyr.png)
now we know that
kinetic energy depends on the mass of object and it is product of mass and square of the speed.
Here we can say that if mass is doubled then kinetic energy also get double and if mass is decreased then kinetic energy also decreases
This type of relationship is known as direct relationship and here since it shows direct relationship so correct answer will be
Kinetic energy and mass are directly proportional to each other
