Unformatted text preview: Yes it is a valid assumption. The ball has a pretty small surface area, which creates very little drag at these relatively low velocities and therefore isnt very significant to the calculations for this experiment. Also, factoring drag into the equations for velocity would make the equations too difficult for a Physics I course. 3. Why was it important that the spring tension not be changed? If the spring tension is changed, the velocity of the ball will change....
