Centripetal acceleration is the acceleration of an object moving in a circular path. It is defined as the change in velocity of an object over time, and it is always directed towards the center of the circle in which the object is moving. In this lab, we will be studying the relationship between centripetal acceleration and various factors such as mass, radius, and velocity.

To begin the lab, we will need to set up a simple apparatus to measure centripetal acceleration. This can be done using a circular track or a circular table with a smooth surface, a mass on a string, and a timer or stopwatch. The mass should be attached to a string and allowed to swing in a circular path around the center of the track or table.

Next, we will need to measure the radius of the circular path and the velocity of the mass as it moves around the circle. The radius can be measured by placing a ruler or tape measure along the circumference of the circle and measuring the distance from the center to the mass. The velocity can be measured by timing how long it takes the mass to complete one full revolution around the circle.

Once we have measured the radius and velocity, we can calculate the centripetal acceleration using the formula: a = (v^2)/r. This formula tells us that the centripetal acceleration is equal to the velocity squared divided by the radius.

Now that we have a basic understanding of how to measure centripetal acceleration, we can begin to explore the relationship between centripetal acceleration and various factors. For example, we can vary the mass of the object on the string and see how it affects the centripetal acceleration. We can also vary the radius of the circular path and see how it affects the centripetal acceleration. Finally, we can vary the velocity of the mass and see how it affects the centripetal acceleration.

By varying these factors and measuring the resulting centripetal acceleration, we can gain a better understanding of the physics behind circular motion. This knowledge can be useful in a variety of practical applications, such as designing roller coasters or understanding the motion of planets in orbit around the sun.

Overall, the centripetal acceleration lab is a fun and educational way to explore the principles of circular motion and gain a deeper understanding of the forces at work in the world around us.

Centripetal Acceleration Lab

Laboratory 6 University Physics 215 Objective: In this experiment, we will learn how why a centripetal force is necessary for a circular motion. Figure Three: This graph demonstrates speed 3 measured by the accelerometer and gyroscope. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower, I would prepare several masses e. This gives us the time it takes for the mass to complete a full revolution at the given diameter. The student will calculate the theoretical centripetal force and the experimental centripetal force. As the length of the string for the flying toy increased, Î¸ decreased in both trials for the cow and bat. Gravity and friction also affect the speed of the marble going down the ramp.

Below are data tables in which I have documented my measurements. The weight of the washers a. Some are mentioned in the lab itself, but one major one is not, and during the experiment I noticed its effect and hypothesized that it would be significant. In order to get relationships between the variables mentioned above, this experiment was divided into two parts. Obviously this is not true. Calculate the time for the Bob revolution in any repeat of the process you've made.

Tangential velocity is the name given to this. Data In this lab, I will investigate centripetal force by swinging a weight i. In Experiment A, the radius of the path length of the string , along with the mass was kept constant, and the relation between centripetal force and square of frequency was determined. Column a records the radius, in that just before I finished swinging the stopper, I clamped down on the string to mark its length. Centripetal Acceleration and Force Lara de Almeida and Abigail Jarratt Physics 221 Section 4 Aaron Kirby Performed: September 15, 2016 Submitted: September 22, 2016 Introduction The objectives of this experiment included centripetal acceleration, centripetal force, centripetal acceleration of a mass, centripetal force on a mass, and verification of the equations for centripetal acceleration and force. The physics 182 test was about the work-energy theorem and the impulse momentum theorem. We measured the distance from the bottom of the weight to the floor, and then let the weight fall to the floor, and measured the time it took to do so.

An example of body moving in a circular path at a constant speed is a carousel. MATERIALS: Vernier data-collection interface string Logger Pro or LabQuest App ring stand or support rod Vernier Photogate rod to support Force Sensor Vernier Dual-Range Force Sensor slotted lab masses right-angle clamp metric tape mass hanger ANSWER THE QUESTIONS: 1. Any change in velocity, including changes in speed, direction, or both, is referred to as acceleration. Then, search for the average time per trail revolution. Because there is a change in the vector quantity of velocity, the body is accelerating; thus, any body moving in a circular path with a constant velocity will continually undergo centripetal acceleration centripetal meaning center seeking.

Student also research what Centripetal Acceleration is and how it relates to Centripetal Force. This centripetal force causes the motion that results in the circle path. For instance, when the bat had a length of 0. Js2 Im point slope Î”Im p. Therefore, reinforcing the importance of thermodynamics concepts and their role in our society. We moved the masses in towards the centre of the rod and continued to repeat the falling mass measurements.

Data Table 2 is a bit less boring than 1. The analysis tool helps find the values of mean, acceleration, and velocity during that time period. RESULTS When starting the lab the first thing to do is to measure the cylinder properties the bob in table one. Measure and record the distance in data table. First, average speed is distance divided by time, and we use it to describe the motion of an object moving at changing speeds.

The charge to mass ratio of the electron is measured by accelerating electrons through a uniform magnetic field with a constant potential difference. According to Newton 's Second Law, then the centripetal force Fc should be the mass of the object m times the centripetal acceleration. In the absence of the centripetal force the ball would no longer be kept in orbit and will eventually be driven in the direction of its tangenti al velocity v. It is therefore called Centripetal Acceleration. So, an object traveling at constant speed in a circular path is undergoing an acceleration.

In this lab students will explore multiple variables of centripetal acceleration. This the 'force ' that you feel when you take a turn in a car or on a roller coaster. First Law of Thermodynamics. The slight difference between the percentages could have been a result of parallax, instrument resolution, environmental factors, and the lack of trials. Objective Students will determine the angular velocity of a spinning object using varying hanging and rotational masses and varying radii. Learning Goals This lab takes about 70 minutes.
