ABSTRACT:
The main idea of this lab today is to gain the better understanding of the tension force. In this experiment, we are design to test the magnitude and the direction of the force is exerted on an object of a body to induce the circular motion upon the object. Today, we will perform two experiments; circular motion and rotational motion. Circular motion is a body of an object moving in a circle with constant speed. In this procedure, the magnitude of its velocity is not changing but the direction of its velocity is constantly changing. Also the acceleration of the body is directed radially inward, toward the center of the circle. Newton’s 2nd law is applying in this experiment order to have acceleration toward the center of the circle. Rotational motion, we will use a body with a rubber stopper tied to a cord, which passes through short tube and from which a load is suspended. We will hold the tube with our hand, and generally swing the stopper overhead (watch for your head).
INTRODUCTION:
In this lab, we will perform two procedures. First circular motion is the motion of a body moving in a circle with the same speed. Also the motion will link with velocity, mass and radius of an object. There will be force apply to the change of an object as it moving. There are four component of motion; displacement, velocity, acceleration, and time. In this lab, we will apply Newton 2nd law help to calculate acceleration move toward the circle. When an object moves around by motion, it will influence by another force call centripetal. Centripetal force is a force keeps the object moving in curve. Second procedure that we will experiment today is rotational motion. In this experiment, we will use the rubber stopper attached to the string. The string will pass through a plastic tube. We will examine of the string radius. We will find out the factor that affects the motion of rubber stopper in rotational motion.
