The scientific method. When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
Yes, if the mass starts at rest, <u>the change in speed will be equal the final speed</u>, because:
Δv = Vf - Vo
How Vo (Initial velocity) is equal zero, we simplificate:
Δv = Vf
Then, the change of the speed, if the mass starts at rest, will be equal to final velocity.
