News Letter- Danny Kalke & Tanner Dalton


Recommended Posts

Amazing! simply Amazing!, students at Irondequoit High School have recently calculated the acceleration of an object due to gravity. they were able to do this through a specialized lab in which one student held a ball to the ceiling while the other measured the distance to the floor. they then timed how long it took the ball to fall to the floor using a stopwatch.  after finding the average time of three trials the students used a kinematic equation to find the acceleration of the ball( d=ViT +1/2(A)(T)^2). once found the acceleration was used in the percent error equation to find the difference between the calculated value and the accepted value(9.81m/s^2). There have been rumors that these same students also found a way to measure one's jumping displacement.
