How does increasing the mechanical energy by winding up a toy more affect the speed?
It makes it go faster because there is more energy
It makes it go faster because there is less energy
It makes it go slower because there is more energy
It makes it go slower.

Students are playing with wind up toys. How can they tell which car is the fastest?
The car that travels the same distance in the least amount of time is the fastest.
The car that travels the shortest distance is the fastest.
The car that travels a longer distance in the greatest amount of time is the fastest.
The car that travels the longest distance is the fastest.
