# Can we use a spring to accurately measure force?

Variables Independent: Mass of the weights (Newtons). Dependent: Extension of the spring (centimeters). Controlled: The same type of spring (the size and strength of extension) is used for every trial, so the difference between each weights can be observed more efficiently.The number of weights added onto the spring for each trial. Summary Method ====================Figure 1: … Continue reading
