Y Velocity in the air

Here is the graph of the y velocity versus time after Cam has left the swing. Here the data also represents an object in projectile motion. The velocity is shown decreasing at a pretty consistent rate. Using a linear trendline we can see that indeed the data is sloping downwards. The slope of this function gives us the constant acceleration the object is experiencing. The slope of our graph is -9.748 which is extremely close to the accepted value of acceleration due to gravity which is -9.810. This makes sense because an object in projectile motion experiences a constant acceleration due to gravity which is demonstrated in our data. The slight difference between our value of acceleration and the accepted one could be due to air resistance affecting Cam’s acceleration in the y-direction.
