Hi!

in **[this exercise]**(https://gist.github.com/aa9fc63a7fb5eab530935c1e408fab18), task 11 requires me to

*“Define a final function called get_work that takes in mass , acceleration , and distance . Work is defined as force multiplied by distance. First, get the force using get_force , then multiply that by distance . Return the result”*

so I quoted **get_force** function when defining **get_work** and wrote

def get_work(mass,acceleration,distance):

return get_force*distance

the output showed error. since get_force =mass*accelearation, I then wrote:

def get_work(mass,acceleration,distance):

return mass * acceleration * distance

the output showed the correct result—but I don’t quite get why quoting get_force function didn’t work?

Appreciate the answer!
