Examples of objects that move in circular motion include a yo-yo being swung in a circle, a planet orbiting around a star, a swinging pendulum, and a car negotiating a roundabout.
The study of why objects move is dynamics, whereas the study of how objects move is kinematics.
Objects move when their balance is changed.
Examples of forces at work include gravity pulling objects toward the Earth, tension in a stretched rubber band, a person pushing a box across the floor, and the magnetic force between two magnets. These forces can cause objects to move or change shape.
Push, gravity, and friction are all examples of forces that can cause objects to move or change their motion. Push and gravity are forces that can cause objects to accelerate, while friction is a force that opposes motion and can cause objects to slow down. They all involve interactions between objects and the forces acting on them.

No
Forces don't move. Objects move. All moving objects have momentum as well as kinetic energy.
Planets, moons, asteroids, and comets are some examples of large objects that move around a star, such as the Sun in our solar system. These objects orbit the star due to gravitational forces and can vary in size and composition.

An object can still move even if the action and reaction forces are equal because they act on different objects. The equal forces produce opposite accelerations on the two objects, causing them to move in opposite directions. This is described by Newton's third law of motion.
No, it can occur just about anywhere. For example, many objects move in more or less circular objects around some other object that attracts them.
