For objects to continue in circular motion, a net force must be acting on them, based on newtons 2nd law. These stations contain problems covering newtons 2nd law, and align with the science teks 8. This force is directed towards the center of the circle, and.
The second law describes the response of the object to a force being applied we know that different objects respond differently to the same magnitude of force. The acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net. There are three difficulty levels for these problems.

Each problem differs in terms of the given quantities and the unknown quantities. The direction of force f rightward, the direction of friction force leftward the direction of friction force is opposite with the direction of objects motion. Based on newtons 1 st law, objects moving in circular motion, would fly off in a straight line if released. Choose rightward as positive and leftward as negative. Forces and newtons laws of motion there is nothing either good or bad, but thinking makes it so. It is the acceleration of an object produced by an action or force which is directly proportional to the magnitude of the net force in the same direction and inversely proportional to the object mass.
