I was absent from school for 3 days and my teacher gave this worksheet to me. I have no idea what I'm doing on it. Can anyone please help me with this? Thanks.

Trying working out theoretically what the acceleration of each of those objects would be.

Sure, I would be happy to help you with your homework on circular motion, center of gravity, and rotational motion. These are important concepts in physics that involve the motion of objects in a circular path and their balance and movement around a central axis.

Let's start with circular motion. This refers to the motion of an object along a circular path, where the object moves at a constant speed but changes direction continuously. In order for an object to move in a circular path, there must be a force acting on it towards the center of the circle, known as the centripetal force. This force is what keeps the object moving in a circular path and prevents it from flying off in a straight line.

Next, let's talk about center of gravity. This is the point on an object where the force of gravity can be considered to act. In simpler terms, it is the point at which an object's weight is evenly distributed in all directions. For most objects, the center of gravity is located at or near the geometric center of the object. However, for irregularly shaped objects, the center of gravity can be located at a different point.

Finally, rotational motion refers to the movement of an object around a central axis. This can be seen in objects like wheels, tops, and planets, where the object rotates around a fixed point. Similar to circular motion, rotational motion also involves a centripetal force that keeps the object moving in a circular path.

Now, for your homework, you may be asked to solve problems related to these concepts, such as calculating the centripetal force required for an object to move in a circular path or determining the center of gravity for a given object. It may also involve applying these concepts to real-life situations, such as the motion of a spinning top or a planet orbiting around the sun.

I hope this helps you understand the concepts of circular motion, center of gravity, and rotational motion better. If you have any specific questions or need further clarification, please let me know. Good luck with your homework!
