Determining Acceleration Due to Gravity

We started off Tuesday's class by reviewing the Cart on a Ramp lab and going over any problems that we had. Some key concepts that were needed to complete the lab are:

• Know how to draw and describe position, velocity, and acceleration graphs.
• Have a good understanding of how to use the LabQuest, and to be able to curve fit the different types of graphs.
• Calculate the percent difference.

From this lab we learnt that an object on an incline that does not change will always have a constant acceleration due to the force of gravity.

After reviewing the Cart on a Ramp lab, we then started on a new lab, Determining g on an Incline. This lab consists of Mr. Banow saying extrapolate a few times, and changing the incline of the slope to help us determine the value of gravity (g). To do this we use the LabQuest, a ramp, the motion detector, and the dynamics cart.
