Answer:
a frisbee flaying in the air
Step-by-step explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion. 
Mathematically, kinetic energy is given by the formula;

Where;
- K.E represents kinetic energy measured in Joules. 
 - M represents mass measured in kilograms. 
 - V represents velocity measured in metres per seconds square. 
 
Hence, an example of kinetic energy at work is a frisbee flaying in the air because it would possess energy due to its motion in the air.
