I learned about circular motion and gravitation. Circular motion is motion in a circle or radius, we learned how to find the frequency, velocity,centripetal acceleration and force of an object moving in a circle. Centripetal means directed towards the center of the circle.Objects moving in uniform circular motion will have a constant speed not a constant velocity, the magnitude of the velocity of a body on a uniform circular motion is constant and its direction is always changing.Next was universal gravitation, which is when the gravitational force varies inversely with the square of the distance between two objects. The law of Gravitation states that every object attracts each other. Last there is Gravitational Acceleration which is when the weight on the object on the Earths surface is equal to the gravitational force between that object and the Earth.

I found difficult when finding the Gravitational Acceleration and force is converting the km to m, and also the scientific notation messes me up a lot too. Finding the Circular motion has been a little difficult but I understand it.

My problem solving skills have gotten greater by thinking more outside the box when mixing the equations to find static friction or something. That had showed me that there is an answer its not just unsolvable. When I kept on thinking it kept on making more and more sense to me. I think I need to work on using scientific notations in problems.
