Centripetal Acceleration Objectives Measure the trend in the force exerted by a string on a mass in circular motion when the angular velocity is varied as the radius is held constant. Measure the trend in the force exerted by a string on a mass in circular motion when the radius is varied while the angular velocity is held constant. There is a weight holder at each end of the arm. One of the weight holders is fixed. This slideshow requires JavaScript. As the radius of the motion increased the frequency decreased. Since radius and frequency are inversely proportional to each other, the increase in radius, increases the value of the denominator, in result as the constant is the tension, the frequency decreases.

As the number of stoppers increased, the frequency decreased.

The relationship between the number of stoppers and the frequency is also inversely proportional, since the constant will remain centripetal force.

As the centripetal force tension increased, the frequency increased. The relationship between the centripetal force and frequency is directly proportional, because the Centripetal acceleration lab essay and the radius in the circular motion are always constant.

Through this analysis, and the understanding of the relationships the equation of frequency is, Conclusion The purpose of this mission was to help Hercules understand the relationship between frequency and radius of the motion, the mass of the sac, and the magnitude of the force causing the motion.

The hypothesis was valid, as the data and analysis showcased the following results: As the radius of the motion increased, the frequency decreased. As the hanging mass tension increased, the frequency increased.

## The Centripetal Force Requirement

This is clear since the radius and the mass of the object have inverse relationship with the frequency, the results established are true. Since the centripetal force and the frequency have a directly proportional relationship, the results established were valid. In this experiment some sources of error could have been, when the counter who was counting up to 20 cycles, either counted extra or less number of times.

The timer could have also stopped the time before or later when the experiment was being done. To solve this problem, the counter could hold a paper on the edge of the motion.

As the stopper would be spinning, every time it hit the paper, it would count as one. Being able to hear 20 hits on the paper would give an accurate result of time. Another error could be that of the speed at which the string was spinning at.

The speed was not constant for the entire motion, since the string would sometimes be changing radius. In this case the rubber stopper wanted to move in straight, however due to inertia, the stopper moved in a circular motion. This is true in this experiment as it was studied that the net force acting on the rubber stopper was in the direction of the acceleration of the stopper.

When the mass hanging at the bottom puts tension on to the rubber stopper of certain amount, the rubber stopper exerts the same amount of force on to the hanging mass, except in the opposite direction.Centripetal Force Lab Purpose: 1.

To study the nature of Centripetal Force 2. To measure the relationship between Centripetal Force, mass, and velocity The force causing the centripetal acceleration, the centripetal force, must obey Newton’s Second Law: Calculate and record the centripetal speed and the centripetal force.

Compare the. Published: Mon, 5 Dec Investigate the relationship between centripetal force and velocity in circular motion, when a stopper is swung with a string in which different weight hangers are attached to.
