Forces in 2D and Circular Function

In our first lab of the second semester, we used the kick discs to test the nature of normal, gravitational, and tension forces. We measured the x and y values and used SOH CAH TOA to find the magnitude. These x-components and y-components are independent from one another. By adding up the x-components and the y-components, we can calculate the net force to analyze these forces in 2D. By spinning the disc, we created a centripetal force.  For an object to move in a circle, you need to apply one force toward the center--this motion causes acceleration. To orbit means to travel in a circular path. Satellites and even other planets orbit the earth through the centripetal force of gravity.
