### Determining g Lab Deliverable

BREAKING NEWS ON GRAVITATIONAL ACCELERATION IN IRONDEQUOIT

Students taking Regents Physics in Irondequoit High School have determained a way to calculate gravitational acceleration quickly and effectivelly. They preformered a lab in which they produced evidence of this.

In forming groups of three, the teams gathered a tape measure, stopwatch, and a foam ball. One group member stood on a stool while the other measured the distance the ball would be dropped from the member standing on the stool. The member dropping the ball uses the stopwatch to eliminate delay error once the ball was dropped. The team calculated the time it took for the ball to be dropped to the time it hit the floor. Using the time, the distance it fell and the initial velocity of 0 m/s, the students used the kinematic equation d=vit+1/2at^2 to determain the acceleration. Afterwords, they calculated their percent error to be 29.7%.

Using this method, now anyone can learn to calculate the gravitational acceleration of a falling object.

### Physics Intro Assignment

Wish you were in my science again this year! Good luck with softball in the spring!

I'm taking physics for the same reasons! Good luck with swimming this year!
