Answers
Let’s pretend you have a task to do -- move a very heavy bag of groceries from the grocery store to your Grandma’s fourth-floor apartment down the street. It might sound easy but what if you had to do it without using a shopping cart? What if there was no elevator and you had to walk up all those stairs? That is exactly what would happen if we didn’t have simple machines. Shopping carts, the ramp outside the store, and the pulleys in the elevator are all simple machines.
